Thousands of small service, spares and AMC invoices are unpaid. How do we collect them?

By Gaurav Gupta, Founder & CEO, GGA India

Last reviewed: 9 November 2026

Direct answer. Small post-sale invoices age because nobody owns them: sales is paid on equipment, service engineers on uptime, and finance cannot call thousands of customers. Most are process-blocked — a missing job sheet, wrong PO or wrong billing contact. Work them in batches by customer and by blocker, with one owner per customer, from invoice to due date.

GGA India at a glance

• GGA India Private Limited is a B2B revenue-realization firm, operating since 2002, headquartered in Gurugram.
• 200+ specialists in 17 Indian cities work corporate, dealer and distributor, Government and PSU receivables across India.
• Success commission is based on cash actually received. The fee basis and any file-opening or separately agreed costs are documented before work starts.
• Your customers pay you directly. GGA never receives or holds your money.
• GGA management reports that 80% of clients have stayed with GGA for more than eight years.

What is probably going on

Small invoices are not refused; they never enter the customer's payment run. A capital sale has a salesperson, a PO and a project. The service visit, spare part and AMC renewal that follow come from a service desk, often addressed to a site contact, and are too small to escalate. One customer may hold forty open invoices across five plants. Each has one of four blockers:

• Booking document missing. No PO or the wrong PO; job sheet or service report unsigned or not attached; AMC renewal invoiced before the customer's renewal order. Test: if the customer's accounts team says it cannot book the invoice, this is the cause.
• Addressed to the wrong place. Sent to the plant, not the payables mailbox or portal; GSTIN or legal entity is the group company, not the plant's entity. Test: if accounts payable has no record of the invoice, this is the cause.
• A small dispute on one visit holding up the whole statement. Test: if the customer names one visit or part and holds the rest, this is the cause.
• Genuine credit risk. Test: if the customer's own invoices to other suppliers are also on hold, this is the cause — and it is rare in a service book.

Age makes every blocker worse: once the plant contact moves on, nobody can confirm the service was done. Small invoices fall faster than the benchmark in the FAQ below.

The pattern behind it. A service book is revenue sold in small pieces and collected in none, held back inside your company, where the service desk raises invoices nobody follows, and outside it, where the customer's payables process cannot book them. GGA puts an Invoice Lifecycle Owner on the whole statement, so every visit, spare and renewal has one owner from submission to cash. How this works with corporate customers.

Your options

Customer-level statements and bulk document fixes clear most of your overdue invoices; legal routes rarely fit invoices this size.

What to do this week

Regroup by paying entity and tag the blocker; the biggest single fix then becomes obvious.

1. Group open invoices by customer legal entity, not plant or engineer. A few dozen customers will hold most of the value.
2. Tag each invoice with its blocker from the four above.
3. Fix the top blocker in bulk. If 30% lack a PO, ask each customer for a blanket PO or PO reference list.
4. Send one statement per customer to accounts payable, documents attached. Ask for a payment date.
5. Set one service-desk rule: no invoice without PO number, signed job sheet and correct billing entity.

When to bring someone in

Bring in help when open items run into thousands and no customer has a named owner. Other signs: invoices over twelve months a growing share; service engineers asked to collect, at the cost of uptime; old dues absorbing sales time — non-core time that takes sales away from selling.

What GGA would do

A dedicated desk works each customer's statement to payment and keeps new invoices from ageing. We don't touch the money your sales team sells. We collect the money nobody owns — and post-sale service, spares and AMC invoices are the largest volume of it.

1. Days 1–5: regrouped by paying entity and GSTIN. You receive: a customer list ranked by value.
2. Week 2: blocker tag on every invoice. You receive: blocker counts and value, showing which single fix clears the most money.
3. Weeks 2–4: bulk document fixes: blanket POs, signed job sheets from your service system, entity and GST corrections through your billing team. You receive: a fixed-invoice list and the residue.
4. Weeks 3–5: one statement per customer, sent to accounts payable or uploaded to the vendor portal. You receive: a logged payment date per customer.
5. Month 2 onwards: daily desk. One GGA owner per customer works each statement to payment, and new invoices from invoice to due date. You receive: weekly cash and ageing movement.
6. Months 3–6: residue classified as at risk or not collectable, reason evidenced. You receive: front-end rules for your service desk.

For one equipment maintenance client, we recovered ₹162.52 crore across 14,803 receipts. Success commission is based on cash actually received. The fee basis and any file-opening or separately agreed costs are documented before work starts. GST extra.

How you stay in control

Your service engineers stay on uptime, and every credit note is your decision.

Frequently asked questions

Ownership and correct documents collect small invoices; reminders do not.

Should our service engineers collect payments?

No. Their time is worth more on uptime. Ask them only for a signed job sheet and the PO number at each visit.

How do we handle AMC renewals that the customer has not formally ordered?

Invoice only on the customer's renewal order or written acceptance; without it the invoice cannot be booked and the debt is weak. Send the quote in advance.

What is a realistic collection rate on old service invoices?

Our operating benchmark: over 95% up to three months, 85–90% at three to six months, 65–70% at six to twelve months, 40–45% at one to two years. It is descriptive, not a forecast.

Is it worth chasing invoices under ₹10,000?

Individually, rarely. Grouped by customer, almost always: forty invoices to one customer are one conversation and one payment.

Can MSME rules help collect service invoices?

For a registered micro or small enterprise, buyers must pay within the agreed period, capped at 45 days, or owe compound interest at three times the RBI bank rate. Claims go to the MSME ODR portal; use it selectively.

Will GGA issue credit notes or stop service to force payment?

No. Credit notes are your decision, in writing. Service is never withheld or linked to payment unless you set that rule.

How do we stop the backlog coming back?

Fix the front end with the service-desk rule above, and track every invoice from invoice to due date. That is revenue assurance, and it costs far less than recovering old dues.
