Track contractor bills in your books

Approved contractor payables sync to FastBill expense records. Each entry links the amount owed, dates, and business name. Work approval and payment approval stay separate. Shared IDs help your team match bills across the tools.

Connect client bills to project costs

Client work and agreed billing terms create draft sales invoices in FastBill. Related worker bills show project costs. Your team compares client income with those costs. Client billing and worker pay keep separate approvals.

Match payment records to your books

FastBill receives contractor business names, costs, and shared payment IDs from Wingspan. Finance uses these fields to match expense entries with payment records and support DATEV exports.

How FastBill works with Wingspan

FastBill is a German tool for your books. It tracks costs, client invoices, and receipt files. Wingspan manages worker records. A worker record is a payee. It holds the selected Contractor or W-2 type.

A manager reviews contractor work logs. Work approval creates one amount owed. The worker sees an invoice. Your team sees the same amount as a payable. Finance approves payment in a separate step.

Approved payables sync to FastBill expense records. Client bills sync to outgoing sales invoices. W-2 pay uses pay statements and employee payroll runs with tax withholding. Those costs stay out of contractor expense bills.

FastBill records contractor names on expense entries. Payment IDs and status help finance match the books to bank records. Deposit confirmed means the sending bank or provider processed the transfer. The receiving bank handles posting the funds.

Integration workflows

01

Sync approved contractor bills to expense records

Your team approves a contractor bill in Wingspan.

A contractor submits a work log. A manager reviews and approves the work. This creates one amount owed. The contractor sees an invoice. Your team sees a payable. Finance gives separate approval to pay. Approved contractor payables sync to FastBill as draft expense records. The sync sends contractor business names, net amounts, and dates. FastBill logs the cost for your books.

02

Update expense records after pay is sent

Wingspan sends pay to a contractor.

Finance reviews the payable and approves pay. A contractor pay run sends the payment. Wingspan shares status and payment IDs with FastBill. Finance matches the expense entry to bank records. Deposit confirmed tracks sending-bank or provider processing. The receiving bank handles posting funds. Your team tracks returns separately.

03

Turn approved work into client invoices

Your team approves a contractor work log.

A contractor finishes work tasks. A manager approves the work log. Wingspan groups approved work items and agreed rates. For client jobs, Wingspan sends work lines to FastBill. FastBill creates a draft sales bill. A manager reviews the bill. Approving the client bill does not send worker pay. Worker pay keeps separate approval steps.
