Supplier Portal Management

Every supplier portal, handled. Every invoice, submitted.

Coupa, Ariba, Tipalti, Basware, Tungsten, and the custom portal your biggest customer just rolled out. Invoice Butler registers your company, submits invoices, fixes rejections, and watches approvals — so enterprise revenue stops costing you afternoons.

The problem

Your biggest customers are the hardest to invoice.

Win an enterprise deal and the first thing procurement sends you isn't a payment — it's a portal invitation. Registration forms, tax documents, banking details, PO matching rules, invoice formatting requirements that differ from every other portal you're already in. None of it is hard. All of it is time, and it lands on finance the week you're closing the books.

This is the failure mode reminder software can't even see. Upflow and Chaser email a PDF to an inbox — but if your customer runs Coupa, that inbox is irrelevant. The invoice doesn't exist until it's in the portal, correctly formatted, matched to a PO, and approved. Your dunning sequence is politely reminding someone about an invoice their system has never received.

Then comes the silent failure: a rejection for a unit-of-measure mismatch or an expired PO, noticed three weeks later when the payment doesn't arrive. Every portal rejection you don't catch same-day adds a full cycle to your DSO on your largest invoices.

The Invoice Butler way

We live in the portals so your team doesn't have to.

Invoice Butler treats portals as a core collections channel, not an exception. It completes vendor onboarding into new procurement systems, submits every invoice in the format each portal demands, monitors status daily, and when something bounces, it fixes and resubmits — without pulling your team in. Approval stalls get chased with the buyer's AP team directly. You see one status: where the money is.

What the Butler handles

Vendor onboarding, done for you

New customer, new portal? The butler completes registration, banking, and tax setup so day-one invoices don't wait on paperwork.

Invoice submission to any portal

Coupa, Ariba, SAP, Tipalti, Basware, Tungsten, or a homegrown system. Submitted in the format each one demands.

Rejection handling

Format errors, PO mismatches, expired POs: caught same-day, corrected, resubmitted. No three-week silent failures.

Approval monitoring

Daily status checks across every portal. Stalled approvals get chased with the buyer's AP team before they age.

PO and compliance matching

Line items, tax fields, and PO references reconciled before submission, so invoices clear validation the first time.

One view across all portals

Stop logging into seven systems. Every portal invoice's true status, in your dashboard and Slack.

How it works

Live in under a week

1

Share existing portal creds

Securely share existing portal access, or let the butler register your company for new ones. We're fanatic about security (and SOC 2 Type 1 & 2 compliant).

2

Invoices route automatically

The butler knows which customers pay via portal and submits there instead of (or alongside) email.

3

Status checked daily

Submissions, validations, approvals, and scheduled payments monitored across every portal.

4

Exceptions fixed, you stay informed

Rejections corrected and resubmitted; true blockers flagged in Slack with what's needed from you (rarely anything).

Product

Seven portals. One answer to "where's the money?"

Slack conversation: Tom W asks ButlerBot for the LexCorp invoice status, and ButlerBot replies that it is approved for payment and will pay via ACH in four days.

Every submission, rejection, and approval — without logging into a single portal.

We hated managing supplier portals. Now it's completely handled.

Before Invoice Butler I had three hours a week just blocked off to submit invoices to portals. Now I don't have to do that anymore.

FAQ

Common questions

Which portals do you support?

Coupa, Ariba, SAP, Tipalti, Basware, Tungsten, and effectively any portal — including customers' homegrown procurement systems. If a human can operate it, the butler can, too.

Can you handle new vendor onboarding, not just submissions?

Yes — registration, company profile, tax documents, and banking verification. See also our W-9 & Vendor Documentation and Banking Verification pages; portal onboarding usually involves all three.

Why doesn't my dunning software do this?

Reminder tools send emails. A portal invoice isn't an email problem — it's an operations problem: registration, formatting, PO matching, status monitoring. That requires doing work in the buyer's system, which sequence software was never built for.

What happens when a portal rejects an invoice?

The butler reads the rejection reason, corrects the submission, and resubmits — usually same-day. You're notified only if it needs something from your side, like a revised PO from the customer.

Is sharing portal credentials safe?

Credentials are stored and handled under our SOC 2 Type 1 & 2 controls. Contact security@invoicebutler.ai for our security documentation.

Do you also chase the payment after approval?

Yes. Approval isn't cash. The butler tracks scheduled payment dates and follows up with AP if a payment run passes without remittance — see Collections AI Agent.

Enterprise customers shouldn't be the slowest to pay.
