Procurement runs on email attachments, and it shows
In most Zoho-using businesses the buying process leaves the system almost immediately. A requisition is approved somewhere, then a buyer emails three vendors asking for prices. Quotes come back as PDFs and spreadsheets, get compared by hand, and the comparison lives in an inbox. A purchase order goes out as an attachment. Nobody is certain the vendor read it, let alone agreed the delivery date. Goods arrive, someone signs a delivery note, and weeks later an invoice appears - sometimes for a different quantity, sometimes at a different rate, sometimes for a purchase order that was partially cancelled.
Finance then performs the three-way match manually: invoice against purchase order against goods receipt. Where the three disagree, the query goes back out by email and the invoice sits unposted. Vendors chase payment status. Buyers chase delivery status. Nobody has a defensible audit trail of who quoted what and why one vendor was chosen.
What ECOSIRE builds
ECOSIRE builds a vendor and procurement collaboration portal on the Zoho platform, so the entire quote-to-invoice conversation happens on records rather than in attachments. It is built to order against your approval structure, your matching tolerances and your Zoho configuration.
Vendor access without a Zoho seat
Vendors log into a Zoho Creator application, resolved to a Vendor record in Zoho Books and, where you run it, the linked Vendor in Zoho Inventory. Vendors never touch your Books or Inventory interface and never consume a licensed seat. All record access is filtered server-side in Deluge against the logged-in vendor ID, so a vendor can only see their own RFQs, purchase orders, receipts and invoices. Multiple contacts per vendor are supported, each with a role - sales, dispatch, accounts.
RFQ issue and structured responses
A buyer creates an RFQ with line items drawn from Zoho Inventory Items or a free-text specification, sets a response deadline, and issues it to a selected vendor list. Vendors respond inside the portal with unit price, currency, lead time, minimum order quantity, validity period, applicable taxes and any technical attachments. Because the response is structured data rather than a PDF, the comparison screen builds itself: a side-by-side quote comparison across vendors on price, landed cost, lead time and terms, with the buyer's award decision and reason captured on the record. Sealed-response behaviour, where vendors cannot see each other and the buyer cannot open responses until the deadline passes, is available where your procurement policy requires it.
Purchase orders vendors actually acknowledge
Awarding an RFQ creates a Purchase Order in Zoho Books or Zoho Inventory through the REST API, carrying the awarded prices, taxes and terms. The PO appears in the vendor's portal for explicit acknowledgement: accept as issued, accept with a revised delivery date, or reject with a reason. Partial acceptance at line level is supported where you need it. Every acknowledgement is written back onto the PO record with a timestamp, so the delivery commitment is documented rather than assumed. Amendments and cancellations flow through the same acknowledgement loop.
Approvals that reflect your delegation of authority
Requisition and PO approvals run through Zoho CRM Blueprint or the approval processes in Books and Inventory, driven by the thresholds and hierarchy you define - value bands, category owners, budget holders, and escalation when an approver is unavailable. Approvers act from email or from their Zoho app; the portal reflects the resulting state to the vendor. Nothing reaches a vendor before it has cleared your internal gate.
Receipts and the three-way match
Goods receipts are recorded as Purchase Receives in Zoho Inventory, either by your warehouse team or through an advance-shipment notice the vendor submits and your team confirms on arrival. When the vendor uploads their invoice against a purchase order, a Deluge matching function compares three sources: the ordered quantity and rate on the PO, the received quantity on the Purchase Receive, and the invoiced quantity and rate on the submitted invoice. Matching runs at line level with the tolerances you set - an absolute or percentage variance on price, on quantity, and on total - and classifies the result as matched, within tolerance, or exception. Matched invoices are created as Bills in Zoho Books ready for your approval and payment run. Exceptions are held with the specific failing lines flagged, and the query is raised to the vendor inside the portal instead of by email.
Vendor-side visibility that stops the chasing calls
Vendors see their own PO history, receipt status against each PO, invoice submission status, matching outcome with the reason for any exception, and payment status once a Payment Made is recorded in Books. That single screen removes most of the inbound "has this been paid" traffic.
Vendor master, compliance and onboarding
A vendor onboarding flow collects bank details, tax registration, category capability and the compliance documents you require, holding them against the vendor record with expiry dates. Scheduled Deluge functions flag documents approaching expiry so a vendor is not transacted with while their registration or insurance has lapsed. Bank-detail changes are routed for internal approval rather than accepted directly, because vendor bank-change fraud is a real and common attack.
Automation and audit
Zoho Flow drives the notifications - RFQ issued, response due, PO awaiting acknowledgement, receipt posted, invoice matched or held, payment made - and scheduled functions handle reminders and ageing. Every state change is written to the record, giving procurement and audit a defensible trail from requisition to payment without reconstructing it from mailboxes.
Who this is for
Manufacturers and assemblers buying raw materials and components against schedules; construction and contracting businesses running subcontractor and material procurement; distributors and retailers with regular replenishment purchasing; facilities, hospitality and healthcare operators with recurring supply contracts; and any finance team where unmatched supplier invoices routinely delay the payment run.
How delivery works
1. Scoping call. We map your procurement flow end to end - requisition, approval thresholds, RFQ policy, PO issue, receipt process, matching tolerances - and confirm your Zoho footprint across Books, Inventory, CRM, Creator and Flow.
2. Fixed quote. A written scope covering screens, objects, integrations, the matching rule set, assumptions and exclusions, at a fixed price. Changes are quoted before work begins.
3. Build. Development in a sandbox or separate Creator environment against a copy of your configuration, with checkpoints so you review the RFQ, PO and matching screens before they are final.
4. Install in test. Installed into your test setup with a few real vendors and real historical POs, so your buyers and finance team can run a complete RFQ-to-matched-invoice cycle themselves.
5. Production go-live. After sign-off we install into production, load the vendor master and contacts, set the live matching tolerances, and support your first live purchasing and payment cycle.
6. Support. A defect-fix support window is included after go-live; new modules and integrations are quoted separately.
Typical delivery is 2-4 weeks from confirmed scope, at the longer end where approval hierarchies are deep or matching tolerances vary by category.
