Finance and accounting solutions

Financial approvals and invoices —
Signed and authenticated with a full audit trail.

Finance and accounting teams run approval chains that never stop: invoices awaiting sign-off, delegations of authority, expense approvals. Wthaiq gathers these approvals into one digital route. You sign them electronically with confirmed identity, and every approval is documented with a time-stamped audit trail and a completion certificate. So each approval closes with complete evidence, ready for any review.

The challenge

Every amount passes through a chain of approvals, and paper signing holds it up.

Before any amount is paid out, the request goes through a chain of approvals: the account manager, then the department head, then the finance director. And with every invoice, authorisation and expense approval, the cycle repeats on paper; a signature waiting on an empty desk, a document passed from hand to hand. Worse still, many of these approvals go through with no documented time record, so at audit time it is hard to prove who approved what, and when.

Endless approval chains

An expense is not approved with a single signature; the invoice passes through its preparer, then the accounts reviewer, then the department head, then the finance director. Every link in the chain means a document printed, passed along and signed by hand, so approvals are delayed and pile up on desks at the end of every month.

Paper signatures slow down payments

The approver may be travelling or at another branch while the invoice waits for their signature on paper. Payment stalls, the supplier is kept waiting, and early settlement discounts are missed. At period end the requests pile up, and collecting signatures becomes a race against time that is not always won on schedule.

An incomplete audit trail at review time

At every internal review or external audit, someone asks for proof of who approved each amount, when, and under what authority. But paper signatures and scattered messages do not add up to a time-stamped record, so the team spends days assembling evidence and may fail to tie some approvals back to their source.

How Wthaiq solves it

One route for every an approval and a financial invoice.

Ready templates, an ordered approval flow, identity-verified signing, a timestamped audit trail, a completion certificate for every approval, and a tracking dashboard linking approvals to your finance systems.

Ready financial templates

Start from tightly drafted templates for financial approvals, expense authorisations and delegation-of-authority forms, or upload your documents as PDFs and drag signature and approval fields onto them in minutes. Every approval cycle starts from one standard template, so the wording stays consistent and the recurring errors in invoices and approvals disappear.

Electronic signature for approvals and authorisations

Sign approvals, invoices and bank authorisations electronically with an identity-verified signature under the PAdES standard. Every approver confirms their identity before signing, so approving an amount is tied to a real person with a known authority, and the door is closed on denial over who authorised the payment or the mandate.

A time-stamped audit trail and a completion certificate

For every approval a time-stamped audit trail is built recording each step: who created it, who reviewed it, who approved it and when it was signed — each with a trusted timestamp. And a completion certificate is issued for every approval, bringing this evidence together in a single document ready to present at any review or audit.

Review and approval workflow

Order the approval chain exactly as your finance policy sets it out: preparer, then reviewer, then first approver, then final approver. The document reaches each approver in turn automatically, and no amount is paid until every link is complete, so authority is enforced and each level's approval limits are respected.

Approval route

An approvals tracking dashboard

Track every approval and invoice from a single dashboard: what has been approved, what is waiting on a particular approver, and what has missed its date. Send a reminder in one click and know exactly where each payment cycle stopped, so approvals do not pile up at period end and payment dates are not missed.

Integration with finance systems

Connect Wthaiq to your finance and accounting systems through APIs, so the approval cycle starts straight from your system and the invoice comes back signed with its audit trail and completion certificate. Your data stays consistent in one place, with no double entry and no documents scattered between systems.

The user journey

From the approval request to a signed and authenticated invoice.

1

Choose the template or upload the invoice

Start from a ready approval or expense authorisation template, or upload the invoice as a PDF and drag signature and approval fields onto it.

2

Set the approval chain

Add approvers in the order your finance policy requires: preparer, then reviewer, then first approver, then final approver — each within their authority limits.

3

The approvers confirm and sign

Each approver receives the document in turn, verifies their identity with an official document and a face match, then signs off their approval remotely.

4

An audit trail and a completion certificate

With every signature the time-stamped audit trail is updated, and when the chain completes a completion certificate is issued gathering all the evidence of approval.

5

Archiving, tracking and integration

The document is sealed with long-term archiving and returns signed to your finance system, with a dashboard tracking every cycle moment by moment.

Why Wthaiq

Because every amount is a decision to be reviewed, and its effect must be documented.

A verified identity for every approver

Before any manager approves an amount, they pass through an identity check with an official document and a live face match. Every approval is then tied to a real person with a known authority, and the door is closed on impersonation and denial in financial decisions on which spending and obligations are built.

A completion certificate for every approval

As each approval completes, a formal completion certificate is issued bringing the approving parties, their signatures and their timestamps together in one document. You end up with a ready record proving the payment went through its full chain, which you hand to the auditor or the reviewer with no manual gathering of evidence.

A complete time-stamped audit trail — compliance proven effortlessly

Every approval has a time-stamped audit trail recording every action taken on it: creation, review, approval and signature, each with a trusted timestamp in an order that cannot be altered. At any internal review or external audit you know immediately who approved each amount, when, and under what authority. So you prove compliance with coherent evidence, instead of days spent gathering scattered paperwork.

An approval flow that keeps permissions intact

The workflow enforces each level's authority limits: no one approves an amount above their threshold, and nothing is paid before the chain is complete. The invoice moves from one approver to the next in the right order automatically, so approvals stay under control and segregation of duties is preserved exactly as your finance policy requires.

PAdES standing and archiving that lasts

Every approval is signed to the PAdES standard with a cryptographic fingerprint embedded in it, so any later change breaks it and shows. And the document is archived for the long term, remaining verifiable at any audit or dispute years later, without the signed invoice losing its legal standing.

FAQs

What they ask about Finance and accounts teams.

Can I configure the financial approval chain to match our authorities?

Yes. You build the approval chain exactly as your financial policy dictates: preparer, then auditor, then department head, then finance director, with an authority limit at each level. The document reaches each approver in turn automatically, and no amount is paid out before every link is complete, so approvals stay disciplined and segregation of duties is preserved.

How does the audit trail record who approved each amount, and when?

For every approval, the system builds a chronological record capturing each step with a trusted timestamp: who created the request, who reviewed it, who approved it, and the moment of each signature. The record is ordered and cannot be altered, so at any review you can prove who authorised the payment, when, and under what authority — with no manual gathering of evidence.

What is the completion certificate and what does it contain?

The completion certificate is a formal document issued once approval is complete, bringing the approving parties, their signatures, their timestamps and their identity verification details together on a single page. You hand it to the internal auditor or the external reviewer as complete evidence that the invoice or the authorisation went through its full approval chain.

Does the approver need an account or an app to sign?

No. The approver opens their personal link straight from the browser on their phone or computer, verifies their identity and signs their approval, with no app to install and no account to create. That makes approving invoices and authorisations possible even for a manager who is travelling, and cuts the payment cycle from days to minutes.

Does the platform integrate with our finance and accounting systems?

Yes. Wthaiq connects to your finance and accounting systems through APIs, so the approval cycle starts straight from your system and the invoice comes back signed with its audit trail and completion certificate. Your data stays consistent in one source, with no double entry and no scattered documents gathered by hand between systems.

Does an electronic signature on invoices and authorisations hold up at audit?

Yes. Every approval is signed to the PAdES standard with an embedded cryptographic fingerprint that exposes any later change, and is tied to a verified signer identity and a timestamped audit trail. That gives you coherent evidence that the invoice or the authorisation is genuine and intact, which stands up to internal review and external audit alike.

Close every financial approval with an authenticated signature and a full audit trail.

Create the approval or the invoice, set the approval chain, sign it with your team using verified identity, and get a time-stamped audit trail and a completion certificate for every approval — all from one place, connected to your systems.
