Free Trial: 7-Day Digital Invoice & Supply Chain Modules

Before a business commits to new operations software, they want to confirm one thing: does purchasing, inventory, accounting, and (when needed) FBR invoicing work from the same products and customers—not separate spreadsheets? Wise Supply Chain answers that with a self-service 7-day free trial—no sales call required. At signup you choose Digital Invoice (sandbox FBR), Supply Chain Management, or both.

What the trial gives you

Sign up from /trial/signup with your business name, NTN/CNIC, province, address and phone. The account is reCAPTCHA-protected, your password is hashed at rest, and a verification link is sent to your email. The trial only activates after you click that link—which keeps trials one-per-contact and matches the same delivery path our contact form uses.

Once verified, your company is provisioned with your selected modules, a default invoice number prefix, an 18% default tax rate, and an active trial subscription with limited products and customers@if(is_only_digital_invoice()) and invoices@else; each enabled document type (sales invoices, purchase invoices, bill of materials, expenses, payment vouchers) has its own trial plan document limit when Supply Chain is enabled@endif. There is no credit-card prompt. You sign in with the password you chose and start working.

Module choice at signup

The trial signup form has two checkboxes—Digital Invoice (sandbox FBR only) and Supply Chain Management—and at least one must be selected. Pick invoicing alone if you are evaluating FBR compliance; pick supply chain alone for purchasing, GRNs, inventory, production, and accounting; or enable both to see the full purchase-to-sale-to-FBR spine on one platform.

Sandbox-only, by design

When Digital Invoice is enabled, production posting is intentionally disabled for trial accounts. Every validate and submit call you make goes to FBR’s sandbox, so a typo in HS code or buyer NTN cannot trigger a real return. This is the safest environment to learn how the FBR pipeline reacts to your master data—exactly the discipline we describe in our step-by-step FBR API integration guide.

Your token vs the shared lookup token

The FBR sandbox exposes two kinds of endpoints: reference data (HS code list, UoM mapping, customer registration type lookup, tax rates, SRO schedules) and invoice operations (validate and submit). To get you productive on day one, lookups can fall back to a platform-configured bearer when your own token is blank—so dropdowns and code suggestions populate immediately. Invoice validation and submission, however, always use the sandbox access token you paste into FBR Credentials. That separation matters: the invoice the FBR sees is signed with your identity, not ours.

What we recommend you test in seven days

Treat the trial as a checklist, not a tour. The list below is the same one our onboarding sessions follow:

• Set up a supplier and warehouse, then record a purchase invoice or GRN so stock and payables reflect real receipts—not manual stock edits.
• Add a bill of materials for one manufactured SKU if production is in scope, so you can see raw material consumption on a production order.
• Post an expense or payment voucher to confirm accounting entries land in the chart of accounts you expect.
• Create a real customer with the correct registration type and province. This single field drives downstream tax behavior, and is the most common source of FBR rejection errors.
• Add two or three products with the HS codes you actually invoice—not placeholder ones—so the UoM and sale-type dropdowns reflect your real catalog.
• With Digital Invoice enabled: paste your sandbox FBR token, validate and submit one sales invoice, try a debit note, and print one invoice to confirm totals match what FBR received.

Why we ask for email verification

Two reasons. First, it ensures we can reliably reach the person who owns the trial—setup messages, expiry reminders and upgrade discussions all flow over the same channel. Second, it keeps the trial honest: one verified address means one trial, which protects the sandbox quota for serious evaluators. The email is delivered using your platform’s configured SMTP relay (the same SMTP_HOST/SMTP_USERNAME/SMTP_PASSWORD/SMTP_FROM_EMAIL we use for contact submissions), with a Laravel-mail fallback if SMTP is not set.

What happens after seven days

On day eight your trial subscription expires and sign-in behaviour mirrors any other inactive plan—you can still log in to read your data, but invoice creation and FBR submission are paused until you upgrade. Your customers, products, invoices and tokens are preserved exactly as you left them; upgrading simply re-enables write operations and switches you to production posting when you are ready.

Who the trial is for

The trial is built for the same buyers our paid plans serve: SMEs evaluating digital invoice software in Pakistan, finance teams replacing fragile Excel pipelines, and tax consultants who want a controlled sandbox before recommending a tool to their clients. If you fall in that last group, the reseller panel is worth reviewing alongside the trial.

Trial duration, product and customer limits, and the exact set of fallback lookup endpoints may change between releases. The behaviour described here reflects the current Wise Supply Chain trial flow: module selection at signup, email verification@if(is_only_digital_invoice()), sandbox-only FBR, your own token for validate/submit@else, sandbox-only FBR when Digital Invoice is enabled, and separate document limits per type when Supply Chain is enabled@endif, and platform fallback for read-only reference data when your token is blank.
