Signature capture

The goods changed hands. Now you can prove it.

A finger on a screen, a printed name, a timestamp — taken at the loading bay, the store counter or the desk where a laptop is handed over. AWRA keeps the mark on the movement record and prints it on the delivery note, so “we never received that” stops being a matter of who remembers harder.

4 moments

Receipts, issues, custody handovers
and transfers — signed in place.

2 marks

A transfer is signed on the way out
and again on the way in.

0 bars

Signing works with no signal.
The mark rides the offline queue.

The argument this ends

Nobody disputes that stock moved. They dispute who took it.

Three weeks after a delivery, the supplier invoices for 84 filter kits and the site insists 60 arrived. Both sides are certain. Neither has anything to show. What follows is a fortnight of messages, a credit note nobody can justify, and a relationship slightly worse than it was.

Without a signature

Two memories and an invoice.

Supplier, 3 weeks later84 kits delivered on the 13th. Invoice attached.
Site supervisorWe counted 60. I remember the pallet.
SupplierOur driver says he handed over the full load.
FinanceWho received it? Nobody has told me a name.

The system has a quantity. It does not have a person, so there is nothing to check the quantity against. This is settled by whoever gives up first.

With a signature

One record, and it names somebody.

The conversation changes shape. It is no longer “how many arrived” but “Grace signed for 84 at 14:32 — take it up with her”. That is a question with an answer, and it usually takes one phone call.

Where the mark is taken

Four moments where somebody is standing right there.

AWRA puts the pad exactly where a person is physically present and something is changing hands. Not on approvals, not on forms — on handovers. Each of these is a place where the argument, when it comes, is about who took delivery.

The two-signature transfer

Stock that leaves as 100 and arrives as 97 is not a rounding error.

It is a disagreement between two of your own sites, and one signature can only ever record one side of it. So a transfer is signed for twice. The three units that went missing sit between two named people and a pair of timestamps, instead of beside a blank space that finance will eventually write off.

DISPATCH Nairobi Central 100 units loaded Signed — P. Otieno, 07:10 RECEIPT Mombasa Depot 97 units counted in Signed — A. Wanjiru, 19:48 SHRINKAGE — 3 UNITS Between two signatures, not between two blank spaces. in transit — 12h 38m

Signed while it is still pending

The dispatch mark can only be taken before the stock leaves. A signature added after the lorry has gone would be backdating, so that window is shut the moment the transfer moves into transit.

Signed while it is in transit

The receipt mark can only be taken on arrival. Signing for goods before they turn up is a promise, not a receipt — so the receiving window does not open until the stock is actually on its way.

The gap gets an owner

The received quantity and the shrinkage are recorded as their own figures. With a name at each end, the missing three units are a question for two people rather than a line in a variance report.

When the window closes

A signature you can add later is not evidence. It is decoration.

Every mark in AWRA has one window in which it can be taken or replaced, and that window closes when the record is decided. Once somebody has approved, adjusted, rejected or completed a movement, another party has relied on what it said — and a mark added after that point would attest to a decision it was never present for.

Built for the loading bay

A signature pad is useless where the signing happens, unless it works with no signal.

A loading bay is a metal shed, usually with a concrete roof and no coverage. That is precisely where the handover happens. So the mark is not uploaded as a file — it travels as text inside the movement record itself, which means it survives the offline queue on the mobile app and posts when the phone finds a connection on the way out of the yard.

It rides the offline queue

The mark is captured as the person draws it and carried with the movement, so a receipt signed in a dead zone posts intact once there is signal. Nothing is stranded on a device waiting for an upload to retry.

Finger, stylus or mouse

The same pad works on a phone at the gate, a tablet in the warehouse and a POS touchscreen at the counter — and with a mouse on a desktop, for the receipt somebody signs in the office.

Drawn at screen resolution

The stroke is captured at the density of the device it was drawn on, so a signature taken on a high-resolution phone still looks like handwriting when it reaches the warehouse copy, not like a marker pen.

Never a blocker

Signing is always optional. If nobody is available to sign, or the screen misbehaves, the stock movement is still recorded — because a system that refuses the movement is a system people stop using.

Where the mark ends up

Evidence nobody can find is not evidence.

A signature is worth having in the three places a dispute actually gets settled: on the paper the driver takes away, on the record finance opens three weeks later, and in the file an auditor asks for.

On the printed note and the PDF

The mark, the printed name and the timestamp are rendered onto the check-in and check-out documents — on screen and in the PDF that gets emailed or filed. An unsigned document prints as a clean receipt rather than a form with a hole in it.

On the movement record

Whoever opens the receipt weeks later sees the signature beside the quantity, the reason and the person who recorded it — in the same place as the rest of the movement, not in a separate document system.

Behind your own front door

Signatures are held on private storage, never on a public link. Fetching one goes through a permission check first, so a mark is visible to the people in your organization who are allowed to see that movement — and to nobody else.

In the mobile app

The app that took the signature can read it back, so a field team can confirm on the spot that the handover was signed rather than driving back to find out.

Beside the rest of the trail

The mark sits alongside the reason code, the attachments, the actor history and the approval decision — the material an audit asks for, in one record instead of four systems.

Sized and checked on the way in

Each mark is verified as a genuine image and held to a sensible size ceiling before it is stored, so the signature field cannot be used as a back door for arbitrary uploads.

What it is, and what it isn't

Read this part before you put it in a tender document.

Signature capture is a strong operational control and a weak legal instrument. Those are different things, and vendors who blur them cost their customers money. Here is the line, drawn where we would want it drawn if we were the ones buying.

What a captured signature gives you

  • A named counterparty. The printed name and the timestamp travel with the drawing, because a squiggle on its own identifies nobody.
  • A moment. The record shows when the handover was attested to, not just when somebody got round to keying it in.
  • A closed window. The mark cannot be added or swapped once the record has been decided, so it cannot be quietly backfilled to suit an argument.
  • Something to put in front of a person. Most disputes are settled by showing a driver, a supervisor or a custodian their own mark. That is the job this does, and it does it well.

What it does not claim to be

  • Not a cryptographic digital signature. There is no certificate, no key pair and no PKI. If your procurement checklist means signing in that sense, this is not that.
  • Not certified under an e-signature regime. We make no eIDAS, ESIGN or UETA claim for a captured mark, and you should not accept one from us.
  • Not identity verification. The system records the name that was typed beside the drawing. It does not check that the person is who they say they are.
  • Not a substitute for the contract. A handover receipt is evidence about a delivery. It is not the agreement the delivery was made under.

Signing here, e-signing there. A pad is for a person standing in front of you. A signer at a distance — a vendor acknowledging a purchase order, a candidate returning a contract, a supplier completing prequalification — needs a document sent out, tracked and returned, which is remote e-signature and a different mechanism entirely. AWRA does both, and keeps them apart on purpose: see the document e-signature connector.

And where we deliberately did not put a pad. Expense approvals, budget sign-off and procurement authorisation stay unsigned by design. An approval made by a logged-in person, gated on a permission and written to the audit trail is stronger evidence than a drawn mark — and adding a pad on top would make a real control look ceremonial. A signature belongs where somebody is physically handing something over, and nowhere else.

What changes

Fewer arguments, shorter ones, and a delivery note somebody can actually produce.

None of this makes stock stop going missing. What it changes is how long it takes to find out where, and whether the answer holds up when somebody pushes back on it.

Delivery disputes end faster

A named signer and a timestamp turn a three-week argument into one phone call to the person who signed.

Custody has a counterparty

“I never received that laptop” is answered by the handover the custodian marked themselves.

Transit losses get an owner

The gap between dispatched and received sits between two signatures rather than in a variance report.

Audit questions get shorter

The mark, the reason, the actor and the approval are in one record, so producing evidence is opening a page.

Field teams keep working

Signing works with no signal and never blocks a movement, so nobody is choosing between the process and the job.

Nothing new to learn

The pad appears inside the receiving, issuing, custody and transfer screens teams already use.
