From quote to paid: closing the admin leaks in a field service business

Ask a plumber, electrician or installer where their business loses money and almost nobody says “the work”. They say quoting at 9pm, invoices that go out a week late, and the job where nobody can prove what was actually done.

The gap between doing the work and getting paid

A typical service job passes through five stages: enquiry, quote, scheduled job, work done, invoice paid. Each handoff is a place where information gets retyped, and every retype is a delay and a chance to introduce an error.

The quote is written in one place. The job is scheduled in a WhatsApp group. The technician records what they used on paper. The invoice is rebuilt from that paper, days later, by someone who was not there. By then the parts list is a guess.

Four leaks worth closing

1. Quotes that go out slowly

Response time predicts win rate more reliably than price for small jobs. A customer who gets a quote within an hour often stops shopping. If quoting happens after hours, you are losing work you already earned the chance at.

2. No proof of work

This is the expensive one. Without before-and-after photos, a parts list and a signature captured on site, a disputed job becomes your word against the customer’s — and you generally lose that, either in money or in goodwill. Photos and a signature take a technician ninety seconds and settle disputes permanently.

3. Invoices that lag

Every day between completion and invoice is a day added to payment. Worse, the longer the gap, the more likely the invoice is wrong, and a wrong invoice does not get queried — it gets ignored until you chase it.

4. Stock nobody is counting

Parts consumed on jobs but never recorded turn into two problems at once: margin that quietly disappears, and a van that runs out of a fitting mid-job.

Close the loop on the phone, on site

The fix is not more admin discipline in the evenings. It is capturing information once, where it happens:

• Quote built and sent from the field, accepted online by the customer
• Acceptance creating the job card automatically — no retyping
• Technician capturing photos, parts used and a signature on the phone
• Invoice generated from the job card, not reconstructed from memory
• Payment taken by card or a link the customer can actually use

One entry, carried forward. That is the whole idea.

It has to work in a dead zone

Plant rooms, basements and rural sites have no signal. If capturing a job card needs a connection, technicians will “do it later”, and later means never or wrong. Offline capture that syncs when signal returns is not a nice-to-have in field service — it is the difference between having records and not.

A reasonable first step

Do not digitise everything on day one. Start with proof of work: photos, parts and a signature on every job, captured on the phone. It is the smallest change with the biggest immediate payoff — fewer disputes, faster invoices and an honest parts list.

FieldCard FSM runs this whole loop from one account: quotes that customers accept online, job cards with photo and signature capture, delivery notes, invoicing and payment — with pluggable providers including Stripe, Paystack and PayFast.
