Actigy BPO vs other AP models
Short answer
Actigy BPO adds a managed invoice queue and exception review in existing systems. Enterprise providers may offer broader finance programs.

|---|---|---|---|---|---|
| Best for | Mid-sized finance teams | Large enterprises | Routine invoices | High-volume capture | Small, stable volumes |
| Payment approval | Client keeps it | Client keeps it | Rules in the tool | Client keeps it | Your team |
| Exceptions | Resolved to client rules | Resolved in provider programs | Routed to people | Usually returned | Your team |
| Typical pricing | Per FTE by role | Custom contract | Subscription or per invoice | Per invoice or per page | Salary plus overhead |
| Start | Audit, then a paid pilot | Multi-phase transition | Implementation project | Varies | Recruiting and training |

|---|---|---|

Accounts payable outsourcing FAQ
Who are the best accounts payable outsourcing companies?
This list ranks Actigy BPO first for invoice processing with a defined exception queue, review checks and client-held payment approval. It suits buyers who already have accounting tools but need people to run the process. Compare automation products separately: a software subscription does not by itself supply managed follow-up on missing or disputed invoice data.
What is accounts payable outsourcing?
Accounts payable outsourcing moves invoice processing, matching, exceptions and vendor queries to an external team. Actigy BPO runs this work in client systems, and the client keeps payment approval.
Is AP outsourcing better than AP automation?
They solve different problems. Software automates routine invoices, and a team handles exceptions, vendor queries and fixes. Actigy BPO works next to AP tools, so you can use both.
How much does AP outsourcing cost?
Providers charge per FTE, per invoice or a fixed monthly fee. Actigy BPO prices most AP work per FTE by role after a process audit.
Can an AP outsourcing team work in QuickBooks?
Yes. Actigy BPO teams enter and match bills, handle exceptions and prepare payment runs in QuickBooks. The client keeps payment approval and bank access.
What is three-way matching?
Three-way matching compares an invoice with its purchase order and goods receipt before payment. It helps detect mismatches, but does not guarantee that every duplicate or overpayment is stopped. Actigy BPO reviews the agreed matching rules and routes exceptions to the client.
Is it safe to outsource accounts payable?
Assess access, payment authority, bank-detail changes and quality review before outsourcing. Actigy BPO keeps payment approval and bank access with the client and uses agreed review controls. These safeguards do not remove the need for oversight or guarantee that fraud and errors cannot occur.
Can AP outsourcing reduce invoice cost?
It can, depending on volume, exceptions, systems and retained costs. Actigy BPO reported 65% lower invoice processing cost in one anonymized SaaS engagement. The result was not independently audited and is not a forecast for another company. Test total cost on a defined pilot and baseline.
How fast can an AP outsourcing team start?
An Actigy BPO pilot usually starts 2 to 4 weeks after the process audit. ERP or QuickBooks access and approval rules affect the date. The team scales after the pilot meets the agreed thresholds.
