The problem
Dynamics 365 Business Central treats vendors as internal records. Exposing vendor-facing workflows — self-onboarding, invoice upload, PO status lookups, delivery confirmations — means giving external users some path into your Dataverse. Microsoft's answer is Power Pages: a low-code portal platform where your team builds the vendor UI, wires up the data bindings, configures the authentication, tests it, and then maintains it. Done well, that's a real 3-to-6-month project with dedicated Power Platform resources and ongoing license fees per authenticated external user. Done poorly, it becomes one more half-finished internal tool. Either way, most Dynamics 365 mid-market customers skip the project entirely and let vendor management happen in email.
The solution
Sourced is a ready-to-deploy vendor portal that connects to Business Central through the Dataverse API. You get the supplier-facing UI out of the box — self-onboarding flows, invoice upload with OCR, PO and payment status visibility, ASN submission, compliance document management — white-labeled to your brand. Configuration takes days, not months. Data flows bi-directionally with Dynamics: vendor records, vendor bills, goods receipts. Your Power Platform team stays focused on the internal workflows that matter; supplier self-service is handled.

Dataverse-native sync — Business Central stays your system of record
No per-external-user Power Pages license costs — pricing scales with volume not headcount
How the portal works with Dynamics 365.
Supplier invite and sign-in
Your team sends the invite from Sourced. The supplier lands on your white-label portal, creates credentials (or signs in via Microsoft Entra ID external identities if configured), and starts onboarding.
Guided self-onboarding
The supplier fills in company details, tax info, banking details, required certifications, and uploads compliance documents. Validation runs inline. Completed profiles sync to the Dynamics 365 vendor table as new or updated records.
Live PO and invoice status
The supplier sees every PO routed to them, with line items, delivery windows, and payment status — all pulled live from Dynamics 365 via Dataverse. When BC updates a vendor bill status, the portal reflects it in real time.
Respond to RFQs and RFPs
The portal is where suppliers receive new RFQs and RFPs, submit quotes with line-item pricing, attach technical documents, and ask clarifying questions. Awarded quotes create the PO in Business Central via Dataverse.
Two-way messaging per transaction
Each PO and each RFQ carries a structured conversation thread — a supplier messaging hub that replaces buried Outlook threads. Questions, technical clarifications, delivery updates, and supplier responses all live in one auditable place per transaction.
Invoice submission with OCR
Suppliers upload invoices as PDF or XML. Sourced OCRs the document, extracts line items, matches against the PO and posted receipt in BC, flags discrepancies, and creates the vendor bill in Dynamics when matching passes.
ASNs and delivery confirmations
Before shipment, the supplier submits an advance shipment notice with carrier, tracking, and expected arrival. Once received, your warehouse confirms the receipt in Sourced, and the posted receipt record is created in Dynamics automatically.

Why Dynamics 365 customers pick Sourced over Power Pages.
No 6-month custom build, no per-user Power Pages fees
Power Pages is powerful for building any portal from scratch — but 'any portal from scratch' means months of work plus ongoing licensing per external user. Sourced gives you the vendor portal out of the box. Configuration takes days.
Dataverse-native integration
Sourced reads and writes Dynamics data through the standard Dataverse API. Business Central stays authoritative for vendor records, vendor bills, and posted receipts. No duplicate data store to maintain, no reconciliation risk.
Microsoft Entra ID support out of the box
If you want suppliers authenticated through Entra ID external identities (for a familiar Microsoft sign-in), the portal supports that configuration. Or use email-based credentials for suppliers outside the Microsoft ecosystem. Either works.
Works with Business Central and Finance & Operations
The portal connects to both Dynamics 365 Business Central and Finance & Operations / Supply Chain Management. If you operate multi-instance (BC at subsidiaries, F&O at HQ), a single Sourced portal can front both — with subsidiary-scoped visibility per supplier.
Extensible through Power Automate
Every portal event (onboarding complete, invoice uploaded, shipment confirmed) emits a webhook Power Automate can subscribe to. Trigger downstream flows — notify Teams, update SharePoint, kick off approvals — without custom portal code.
Mobile-first vendor experience
Many vendors confirm shipments or upload invoices from warehouses and delivery vehicles. The portal is mobile-responsive by default — works on any phone, no separate app install, no desktop-only workflows.
Suppliers respond to RFQs inside the portal
Vendors receive live RFQs in the same portal they use for status and invoices — submit quotes, upload tech docs, ask questions, and revise bids. Quote data feeds directly into Sourced's scoring engine (no email parsing step).
Messaging per PO and per RFQ
Every PO and RFQ has a structured communication thread. Your buyers and suppliers message within the transaction context — file attachments supported — and every exchange is logged for audit. Power Automate flows can listen on new messages to trigger downstream notifications in Teams.
Frequently asked questions.
Why not just build a portal with Power Pages?
You can. Power Pages is Microsoft's low-code portal tool and it integrates natively with Dataverse. The tradeoffs: the build itself is a real project (3-6 months for a functional vendor portal with self-onboarding, invoice OCR, and scorecards), maintenance is yours forever, and Power Pages charges per external authenticated user. Sourced gives you the same outcome as a pre-built SaaS: faster time-to-value, no maintenance burden, volume-based pricing. For Power Pages investments that are already underway with other internal workflows, Sourced complements them by handling just the vendor portal.
Does Sourced work with Business Central or Finance & Operations?
Both. The Dataverse API integration is the same pattern. Most of our Dynamics 365 deployments are Business Central; F&O is supported and adds extra mapping for the more complex inventory and warehouse tables.
How does supplier authentication work?
Two options. One, email-based authentication — suppliers set a password on the portal, no Microsoft identity required. Two, Microsoft Entra ID external identities — useful if suppliers already have Microsoft accounts and you want them to use them. Both flows are configurable.
Can we use this alongside existing Power Platform investments?
Yes. The Sourced portal emits webhook events that Power Automate can subscribe to. If you've already built internal approval flows or notifications in Power Automate, they extend naturally to portal events without rework.
How does invoice OCR flow into Business Central?
The supplier uploads the invoice in the portal. Sourced runs OCR, extracts line items, matches against the PO and posted receipt in Business Central via the Dataverse API, and flags any discrepancies to your AP team. Clean matches create the vendor bill in BC automatically. Mismatches sit in the Sourced exceptions queue until AP review.
Are you listed on Microsoft AppSource?
AppSource publication is on our roadmap. The integration itself works today via the standard Dataverse API without an AppSource install. Customers authorize Sourced through a Dataverse service principal.
How do you handle Business Central companies / multi-company setups?
Each BC company connects separately. A single Sourced portal can front multiple BC companies with per-supplier scoping, or you can deploy separate portal instances per company — whichever matches your organizational model.
What happens if we switch ERP later?
Every record Sourced wrote to Dynamics lives in Dynamics and moves with any future ERP migration. Portal-side data (supplier-uploaded documents, RFQ histories, scorecards) is exportable. No lock-in either direction.
Can vendors submit quotes for open RFQs through the portal?
Yes. The portal is bi-directional: it serves as the supplier's view into current POs AND as the place where they can respond to live RFQs. Structured quote submissions flow into Sourced's comparison engine with line-item granularity — no PDF parsing round-trip needed. Emailed quotes from the same suppliers still work and are normalized into the same comparison.
Can suppliers respond to both RFQs and RFPs from the portal?
Yes. The portal distinguishes between RFQs (pricing-first, line-item focused) and RFPs (solution-first, document-driven with structured proposal sections). RFQs show line items with price and lead time inputs; RFPs expose the multi-section proposal form you configured, allowing suppliers to describe their approach, attach technical documentation, propose commercial terms, and submit through structured forms. Both flows normalize into Sourced's comparison engine for your evaluation.
