RazorSync has run scheduling and invoicing for field service companies for years, and its reviewers keep a specific list: no purchase order field even though commercial customers demand one, an auto-invoice on completion that breaks multi-visit jobs, a QuickBooks sync that works one direction, a wish to know which day a truck will already be near an address, and payment processing that resists explanation. RazorSync documents an API, which makes each item a contained build. Five, pictured.
The PO field reviewers keep asking for
Commercial accounts payable bounces any invoice without a PO. A layer captures the PO at booking, requires it for commercial customers, and carries it to the invoice header and the books, so the 30-day clock starts on the first submission.

Three visits, one invoice, zero workarounds
Auto-invoicing on completion is right for one-visit work and wrong for a furnace replacement. A multi-visit board holds billing until the last visit closes, tracks what each visit added, and drafts one clean invoice at the end.

The other direction, watched
A one-way sync means the field and the books drift apart a record at a time. A nightly reconciler reads both sides, carries back what QuickBooks knows and RazorSync doesn’t, and flags the rest with exact values.

Book them for the day you’re already nearby
The routing wish in the reviews is precise: type an address, learn which day you’ll be within a few miles. A scheduling helper reads the week’s routes and answers at booking time, so windshield hours turn back into wrench hours.

The payment trail that explains itself
Processed, deposited, fee’d, matched: a Friday report that reconciles payments to bank deposits with fees itemized, so the processing mystery reviewers describe becomes a ledger anyone can read.

The common thread
RazorSync keeps running the day; the builds close the gaps reviewers name. Each is a contained phase on a short calendar, and the mHelpDesk and OpenPhone lists solve neighboring problems if those are your tools.
