PayChasers MCP with Claude: Faster Collection of Overdue Payments
The short answer
Claude works with PayChasers through the Model Context Protocol, an open standard that acts as a secure adapter between the two. Once connected with an API key, Claude can list overdue invoices, send payment reminders, update client account records and create follow-up sequences, all from plain-English instructions. The organisation controls which actions are allowed.
What is PayChasers?
PayChasers is a finance and accounting tool that automates payment reminders, client management and follow-ups for overdue accounts. Finance teams, accounts receivable staff, credit controllers and small business owners use it to reduce late payments and keep receivables workflows moving without manual chasing. It sits at the centre of how many organisations collect money they are owed.
How Claude connects to PayChasers through MCP
The Model Context Protocol, or MCP, is an open standard that lets Claude use other software securely. Think of it as a universal adapter: it gives Claude a defined way to read information from a tool and take actions in it, with permissions the organisation sets. PayChasers offers an MCP server and a direct API, and the connection is made using an API key.
Once connected, Claude can typically read overdue invoices and client account details, draft and send payment reminders, update account notes and create follow-up sequences. Staff can ask for these things in natural language, such as asking which accounts are more than sixty days late and who should be contacted first.
Permissions and approvals keep people in charge. Access is limited to the actions each workflow needs, and consequential steps such as sending reminders to large accounts or changing payment terms can require sign-off from a named person. Every action is logged so the team can review what happened and why.
What you can automate
Overdue invoice reviews
Each morning, Claude can list invoices past due, grouped by age and value. A credit controller can ask for the accounts over thirty days late and receive a short summary with the largest balances at the top. This replaces time spent filtering reports by hand and helps the team decide where to focus first.
Tailored payment reminders
Claude can draft reminders that match the stage of each account, from a friendly nudge for a first late payment to a firmer notice for older balances. Staff review the drafts for sensitive clients before anything is sent. The result is consistent, professional contact that respects each relationship.
Client account updates
After a call with a customer, an account manager can tell Claude about a promised payment date. Claude can record the note against the correct client account and schedule a follow-up. This keeps the account history accurate without the manager switching between screens.
Follow-up sequences
For clients who regularly pay late, Claude can help build a follow-up sequence with set intervals and escalation points. The sequence can be reviewed and adjusted by the finance lead before it runs. This gives smaller teams a structured collection process they might otherwise lack the time to maintain.
Management reporting
Finance leaders can ask Claude for a summary of collection activity, such as how many reminders were sent this week and which accounts responded. Reports can be generated in consistent formats for monthly reviews, helping leaders spot trends in late payment before they grow.
An end-to-end workflow: Overdue invoice recovery with ERP and Microsoft 365 alignment
TriggerEach Monday at 8am, or when an invoice passes its due date by 14 days.
Claude pulls the list of overdue invoices from PayChasers through the connection.
Claude cross-checks the list against payment records in the organisation's ERP to remove invoices already settled.
Claude drafts a reminder for each remaining account, tailored to how long the balance has been outstanding.
The credit controller reviews drafts for accounts above an agreed value and approves them in Microsoft 365.
Approved reminders are sent through PayChasers and Claude logs the actions to the client record.
Claude posts a weekly summary to the finance team channel in Microsoft 365.
OutcomeTypically, finance teams spend less time chasing invoices already paid and more time on accounts that need attention, with a clearer audit trail of every reminder sent.

Frequently asked questions
What does the PayChasers MCP server do?
The PayChasers MCP server gives AI tools such as Claude a secure way to work with PayChasers. It typically allows listing overdue invoices, sending payment reminders, updating client accounts and creating follow-up sequences. It works alongside the direct API, so the right route can be chosen for each workflow.
Is connecting PayChasers to Claude secure?
Security depends on how the connection is designed. We use an API key with the narrowest access each workflow needs, store it securely and rotate it on a schedule. Consequential actions such as large reminders can require human approval, and all activity is logged for audit.

Typically, Claude can read overdue invoices and client details, draft and send reminders, record notes against accounts and set up follow-up sequences. Staff make requests in plain English. The exact actions available depend on the access granted during setup.
How long does setup take?
Timing varies with the complexity of your receivables process and how many systems are involved. A simple reminder workflow can often be designed and tested quickly, while a full process linked to your ERP and Microsoft 365 takes longer. We confirm a realistic timeline during the free audit.
Which plan or permissions do I need?
You need PayChasers access that allows an API key to be issued for your organisation. The specific plan and permission levels depend on your existing PayChasers account. We check what your account supports during the audit and recommend the least-privilege permissions for your workflows.
