An outsourcing proposal runs on a small stock of words, and most of them answer one of six questions. A word that answers one of those questions usually leaves the other five open, which is where the confusion starts: a firm settles the engagement model, then finds that the price, the employment route and the exit were never discussed. An outsourcing glossary is only worth reading if it says what each word changes, so every entry below carries a definition and a pointer to the fuller treatment where one already exists, and the nine words that change a decision on their own get that distinction spelled out.
Outsourcing Glossary: The Six Questions Behind the Words
The six questions are what you are buying, who owns the team doing it, where that team sits, who employs the people on it, how the work is priced, and what happens when the arrangement ends.
They are largely independent of each other. A provider can sell you a managed service, deliver it with a team it owns rather than a subcontracted one, seat that team in a nearby country, employ the people through a local entity, price the work per transaction, and hold you to a three-year term. Five of those facts stay true if you change the sixth.
That independence is why outsourcing and offshoring are two separate answers rather than one, a split worked through in outsourcing vs offshoring. The groups below follow those questions in order. Two of them carry a second load: the contract documents sit with pricing, and the assurance reports sit with the exit.
What You Are Buying
One label in this group is rarely defined in the proposal that uses it, and it decides how much of the work you can still see.
Managed Services
Managed services describes an arrangement where the provider owns the method and the result, not just the hours. You define what has to be true at the end of the month and the service levels that measure it, and the provider decides how to staff and sequence the work to get there.
The distinction that changes a decision is inspection. Under staff augmentation you watch the work happen inside your own system. Under managed services you see reported output, plus whatever inspection rights the contract gives you. If your own process is thin, that trade can be worth taking, and if your process works and you are short of hands it is the wrong purchase. The control split behind that choice is set out in accounting staff augmentation.
The other terms in this group already have their own treatment, so each one below gets a definition and a pointer.
| Term | What it means | Worked through in |
|---|---|---|
| Outsourcing | Moving work to an outside firm, whoever that firm is and wherever it sits. | Outsourcing vs offshoring |
| Business process outsourcing (BPO) | Outsourcing of a defined, repeatable process, usually priced against volumes rather than hours. | Finance and accounting BPO |
| Knowledge process outsourcing (KPO) | Outsourcing of analytical work, where the deliverable is a supported draft rather than a processed transaction. | Knowledge process outsourcing |
| Staff augmentation | Outside people working inside your workflow, under your direction and your review. | Accounting staff augmentation |
| Co-sourcing | A division of labor inside a function you still hold and remain accountable for. | Co-sourcing |
| Record to report | The process that runs from journal entries and reconciliations through to reporting. | Record to report services |
| Procure to pay | The purchasing cycle, from requisition and purchase order through invoice and payment. | Procure to pay process |
Who Owns the Team Doing the Work
Three words describe who owns the delivery team rather than what the team does, and a proposal will often use them as if they were selling points instead of structures.
Shared Services
A shared services center is an internal consolidation. One unit inside an organization performs a function for several offices, entities or departments that each used to do it themselves. Nothing leaves the organization, so on its own it is not outsourcing at all, and the term usually belongs to your client's side of the table rather than to a provider's.
It also gets used to describe a provider's own delivery model, where it means something different: your work is pooled with other buyers' work rather than sitting with named people. Ask which of the two is meant. Pooled delivery decides whether the person who prepared your file last week is the person preparing it this week, and that is a question about continuity rather than about cost.
Captive Center
A captive center is an office the buyer owns and staffs itself, rather than a service it buys from someone else. There is no provider, no service level and no contract to end. There is a legal entity, a payroll, a lease, and a cost to shut it all down if the work stops.
The decision it changes is not the cost per seat, it is what happens when you want out. A provider relationship ends on notice. An entity you own ends on a wind-up that you run and pay for. The same structure goes by global capability center when the office sits offshore, and how far finance and accounting work is actually moving into those centers is covered in accounting outsourcing trends.
Build-Operate-Transfer (BOT)
Build-operate-transfer is a staged route to a captive center. The provider recruits and runs the team on its own entity first, and at an agreed point the team, and sometimes the entity itself, transfers to the buyer.
Everything that distinguishes a BOT from an ordinary outsourcing contract sits in the transfer clause. Read what transfers (the people, their contracts, the equipment, the entity), what triggers the transfer, what it costs on the day, and what happens if you never call it. Without those terms, a BOT is a normal outsourcing agreement wearing a longer name.
Where the Work Sits
One word in this group is a strategy rather than a service, and the rest are geography.
Right-Shoring
Right-shoring is the practice of choosing a location per stream of work instead of choosing one location for everything. Review sits onshore, preparation sits offshore, and a client whose engagement terms restrict where data may go sits wherever those terms allow.
It names a decision rather than a service, and on its own it commits a provider to nothing. When it appears in a proposal, the useful follow-up is which work sits where, under whose supervision, and what moves if a client objects. The location trade-offs themselves are worked through in nearshore vs offshore outsourcing and, for the client-by-client version of the same call, in onshore vs offshore bookkeeping.
The geographic terms are stable, and each one below carries the difference that matters.
| Term | What it means | Worked through in |
|---|---|---|
| Offshoring | Work performed in another country, whether by your own people or a provider's. | Outsourcing vs offshoring |
| Offshore outsourcing | An outside provider in a distant country, usually with limited working-hour overlap. | Nearshore vs offshore outsourcing |
| Nearshore outsourcing | An outside provider in a nearby country, sold on overlapping working hours. | Nearshore vs offshore outsourcing |
| Onshore outsourcing | An outside provider inside your own country. | Onshore vs offshore bookkeeping |
Who Employs the People
This group answers one question with legal consequences: which entity is the employer of the person at the desk. Each term below has a fuller treatment, because the answer changes what you owe and who carries a finding.
| Term | What it means | Worked through in |
|---|---|---|
| Employer of record (EOR) | A company that legally employs a worker in another country on your behalf. | Employer of record accounting |
| Professional employer organization (PEO) | A US co-employment arrangement layered over people you already employ, covering all or a majority of your staff rather than one seat. | PEO vs EOR |
| Independent contractor | A worker engaged directly under a services contract, with status decided on the facts of the work. | EOR vs independent contractor |
| Misclassification | Treating a worker as a contractor when the governing test would call them an employee. | Offshore contractor misclassification risk |
The Documents and the Price
Three documents carry almost everything that will later be argued about, and their names often get used interchangeably in sales conversations.
Master Service Agreement (MSA)
A master service agreement is the frame you sign once. It carries the terms that do not change between engagements: confidentiality, data handling, liability and indemnity, ownership of work product, notice periods, default and termination. Individual pieces of work are then ordered underneath it.
Because scope lives elsewhere, "we have an MSA in place" answers none of the questions about what is included, at what volume, or at what price. The federal banking agencies list the provisions a buyer typically negotiates, from the nature and scope of the arrangement through default, termination and regulatory supervision, and while that guidance is written for banking organizations rather than accounting practices it reads as a usable checklist for a master agreement (Interagency Guidance on Third-Party Relationships: Risk Management, 2023).
A real filed master services agreement, with its schedules named one by one, sits in finance and accounting BPO.
Statement of Work (SOW)
A statement of work is the document that says what is actually being done: the deliverables, the volumes, the turnaround, who supplies what, and what is out of scope. It is ordered under the master agreement, and it is the document that gets amended when the work grows.
The distinction worth importing from public procurement is between describing tasks and describing results. Federal acquisition rules define a performance work statement as a statement of work for performance-based acquisitions that describes the required results in clear, specific and objective terms with measurable outcomes (section 2.101 of the Federal Acquisition Regulation).
Hold your own scope document to that standard. One written in tasks tells you what people will spend their time on. One written in results tells you what you can hold a provider to.
Service Level Agreement (SLA)
A service level agreement is the schedule that turns good service into measured commitments: turnaround windows, rework or accuracy thresholds, response and escalation times, and the remedies attached to missing them.
Two things decide whether one is worth anything. The first is measurement. The same federal acquisition rules require a performance-based services contract to include measurable performance standards and the method of assessing contractor performance against those standards (section 37.601 of the Federal Acquisition Regulation). A standard with no stated method of measuring it is an intention.
The second is what the standard rewards. The banking agencies' guidance warns against negotiating performance measures that encourage processing volume or speed without regard for accuracy or compliance requirements (Interagency Guidance on Third-Party Relationships: Risk Management, 2023). On tax work that is the exact failure mode of a turnaround-time service level, and what a credit can and cannot do once a deadline is missed is worked through in finance and accounting BPO.
The other terms in this group either price the work or paper it, and each has a settled meaning.
| Term | What it means | Worked through in |
|---|---|---|
| Full-time equivalent (FTE) | A contracted seat at a fixed monthly fee, sized as one person's full-time hours or an agreed fraction of them. | FTE vs pay per return outsourcing |
| Pay per return | Pricing per finished return rather than per seat. | FTE vs pay per return outsourcing |
| Service credit | A capped amount the provider owes when performance falls below a service level's stated minimum, which is not the same as missing its target. | Finance and accounting BPO |
| Volume band | A price tier that holds while volumes stay inside a stated range. | Finance and accounting BPO |
| Section 7216 consent | The client's written consent, required by Treasury Regulation section 301.7216-3, before return information is disclosed to a preparer located outside the United States. | How to start outsourcing accounting |
Assurance and Exit
Two different worries live in this group: how you get out of an arrangement, and how you check a provider before you commit to one.
Vendor Lock-In
Vendor lock-in is the state where leaving a provider costs more than staying with one that is underperforming. The workpapers live in their system, the standard operating procedures were written by them, the files are named their way, and the contract charges you to leave.
It is a contract question before it is an operational one. The federal banking agencies say contracts can protect the ability of the banking organization to change third parties when appropriate, without undue restrictions, limitations, or cost. Among the termination provisions that guidance suggests considering are reasonable time frames that allow an orderly transition without prohibitive expense, the timely return or destruction of the organization's data, information and other resources, and the assignment of all costs and obligations associated with transition and termination (Interagency Guidance on Third-Party Relationships: Risk Management, 2023).
It covers banking organizations rather than accounting practices, and those three provisions read the same way against a provider agreement. Check them before the first file moves, because the exit is priced at signature and paid later. What the move itself actually takes is set out in switching BPO providers.
The assurance reports below have precise meanings, and the wrong one answers a question you did not ask.
| Term | What it means | Worked through in |
|---|---|---|
| SOC 1 report | An auditor's report on a service organization's controls relevant to a user entity's financial reporting. | SOC 1 vs SOC 2 |
| SOC 2 report | An auditor's report on controls against the trust services criteria, starting with security. | SOC 1 vs SOC 2 |
| SOC 3 report | A short, freely distributable version of a SOC 2 report, without the detail. | SOC 1 vs SOC 2 |
| Transition management | The planned move of work between providers, or back in-house. | Switching BPO providers |
Which Words Are Worth Arguing Over
Most of the vocabulary in a proposal is descriptive, and arguing about the labels changes nothing. Four things are worth a redline: what the statement of work includes, how each service level is measured, what the exit costs, and which entity employs the person at the desk. The rest follows from those four.
None of it settles whether the work will come back the way you need it. The only way to find that out is to hand a provider a block of your own files and grade the output against work you have already finished.
