Benefits
Why Deepyze for your B2B Vendor Portal?
We work with industry best practices to guarantee real results.
Invoice intake with instant tax validation
Vendors upload PDF or XML files. The system instantly verifies supplier tax IDs, invoice dates, and authorization codes directly against official government tax servers.
Automated purchase order 3-way matching
Automated reconciliation of amounts, unit quantities, and line items against the Purchase Order (PO) and goods receipt slips. Mismatches are rejected on the spot.
24/7 payment status visibility
Suppliers track the exact status of their invoices: received, approved, scheduled for payout, or settled, showing projected disbursement dates and banking channels.
Self-service tax withholding certificates
Instant access to withholding receipts generated by your ERP. Suppliers download PDF records without emailing your finance staff.
Configurable internal approval workflows
Custom approval paths structured by business unit, spending thresholds, and management tiers. Approvers authorize invoices in one click via portal or corporate email.
Contractor compliance & document vault
Maintain corporate charters, insurance certificates, workers comp coverage, and bank account verifications with automated expiration notices.
Process
How we build your B2B Vendor Portal
A clear and transparent method so you always know which stage your project is at.
- 1
Procurement & AP workflow audit
We analyze your purchase-to-pay workflow: PO generation, warehouse physical intake, payment terms, approval ladders, and local tax requirements.
- 2
UX design & web portal engineering
We build the responsive web platform with role-based access control (supplier, internal reviewer, treasury), secure authentication, and drag-and-drop document upload.
- 3
ERP & tax authority integration
We connect the portal to your ERP (SAP, Oracle, Odoo, Softland) to import POs, push approved invoices, and validate tax authorization codes in real time.
- 4
Supplier onboarding & go-live
We train internal finance staff, migrate your active vendor roster, and send automated onboarding invitations with verification guides.
Pricing
How much does it cost?
It depends on the scope: we define it together in a free discovery meeting and send you a fixed-price proposal.
FAQ
Frequently asked questions about B2B Vendor Portal
How does the portal prevent duplicate or invalid supplier invoices?
When an invoice is uploaded, the parser extracts the vendor tax ID, point of sale, and invoice number, verifying its tax clearance with government web services and cross-referencing your database for prior entries.
How much does a custom B2B vendor portal cost?
It depends on the scope: we define it together in a free discovery meeting and send you a fixed-price proposal.
Can it integrate with our existing ERP or accounting system?
Yes. We integrate with SAP S/4HANA, SAP Business One, Oracle NetSuite, Odoo, Tango Gestión, or custom relational databases through REST APIs, webhooks, or secure staging tables.
How much operational time does this portal save the finance team?
Our clients observe over 70% reduction in inbound supplier emails and status phone calls, allowing accounting teams to refocus on cash flow management and commercial terms.
Can it manage insurance certificates and worker compliance for contractors?
Yes. The compliance module tracks mandatory monthly documents such as labor liability insurance and proof of tax status. Expired documentation automatically pauses invoice processing or plant access.
What security measures protect supplier banking details?
Bank account modifications require mandatory two-factor authentication (2FA), company tax ID identity cross-checks, and explicit dual-control authorization from your treasury department.
