Mobile Knife and Tool Sharpening Invoicing App (2026)
Sharpening is a route business: the same restaurants, salons, and shops on a repeating cycle, billed per blade. ShowTheReceipts ($15/mo) saves per-item rates, lets you build the invoice at the counter from a blade count, and bills recurring route accounts on a schedule to a saved card so a quiet week isn't an unpaid one.
How we picked
Entry-plan prices as published in 2026, taken from each vendor's own pricing page or a recent third-party summary. Judged on the mobile sharpener's real workflow — per-item pricing, fast on-site invoicing, and recurring route billing to commercial accounts — not on retail POS, e-commerce, or mail-in order fulfillment.

The route is the asset
Anyone can sharpen. What’s hard to build is forty commercial accounts that expect you on a cycle — and what quietly destroys one is a cycle nobody’s tracking.
An account that drifts from six weeks to twelve hasn’t left. It’s just worth half as much.

Per-item rates saved, invoice built at the counter from a blade count, recurring accounts billed automatically to a saved card.
2. Square — free + processing
Ideal at a market stall; not a route or recurring billing system.
3. Invoice2go — $9.99/mo+
Simple invoicing, one customer at a time.
4. Wave — Free / $16/mo
Free invoices plus light bookkeeping.
5. Jobber — $29/mo (Core)

Price per item, with a stop minimum
- Chef / paring knives — per blade
- Serrated — its own rate
- Shears and scissors — salon versus household
- Clipper blades — groomers and barbers
- Mower and mulching blades — seasonal spike
- Chisels, planes, and specialty tools — by piece
Commercial beats consumer, every time
A farmers-market Saturday is cash and good marketing. A twenty-kitchen route on a six-week cycle is an actual business — predictable, prepaid to a card on file, and largely immune to weather, seasons, and whether anyone felt like coming out that day.
Frequently asked questions
How should sharpening be priced?
Per item by type — chef knives, serrated, shears, clipper blades, mower blades — with a minimum per stop. Per-item pricing is what lets a counter conversation become an invoice in thirty seconds without any arithmetic.
How do I bill a restaurant route?
As a recurring invoice on a saved card, on the cycle you actually run — every two, four, or six weeks. Chasing a small balance at twenty kitchens is the fastest way to make a good route feel like a bad job.
Should I set a minimum per stop?
Yes. Driving to sharpen three knives costs the same as driving to sharpen twenty, and a stop minimum is what makes small accounts either worthwhile or willing to save up a proper batch.
Do I need to track which accounts are due?
Yes, and it's the whole business. Sharpening revenue is a function of cycle discipline — an account that quietly slips from six weeks to twelve has halved its value without anyone deciding anything.
