Key Takeaways for Restaurant Operators
- Automated invoice handling replaces manual data entry, cutting 7–10 hours of work and reducing costly 2–5% error rates for restaurants processing over 200 invoices monthly.
- Building a full OCI invoice workflow involves seven complex steps, yet most operators only complete the first four before resource constraints push them toward a simpler platform.
- Most restaurant operators lack the developer resources needed to maintain OCI flows, which creates backlogs, manual reviews, and delayed financial reporting.
- Jelly delivers the same end-to-end automation, including invoice scanning, Xero sync, POS integration, and price alerts, in under a week with no Oracle expertise required.
- Operators using Jelly report 10–20 hours saved monthly and up to 2 percentage point gross-profit gains; book a demo with Jelly to see results within days.
What You Need Before You Start with OCI
Successful OCI invoice automation starts with a few essentials in place. You need an active OCI tenancy with Document Understanding enabled, supplier invoices arriving by email or as scanned PDFs, a supported POS system for sales data, and a Xero account for accounting integration. Invoice-processing tools sit between invoice intake and the accounting system as a processing layer, extracting data, running validation checks, and sending approved data onward. Without clean data flowing into Xero, gross profit figures stay unreliable and supplier negotiations lack the evidence base needed to protect margins.
Step 1: Configure OCI Object Storage and Email Ingestion
Start by creating an OCI Object Storage bucket that acts as the landing zone for incoming invoices. Configure an email ingestion endpoint, either through Oracle Integration 3 or a custom SMTP relay, so supplier invoices forwarded to a dedicated address land in the bucket as PDF or image files. OCI Document Understanding invoked from Oracle Integration 3 can extract data from PDF invoices attached to vendor emails or uploaded to an SFTP server. Plan for 2–4 days of configuration and testing for a single site. Common pitfalls include inconsistent supplier email domains that bypass ingestion rules and PDF files with embedded images rather than selectable text, which reduce extraction accuracy.
Step 2: Set Up OCI Document Understanding for Line-Item Extraction
OCI Document Understanding’s pretrained invoice key-value extraction model extracts header-level fields such as CustomerName, InvoiceId, VendorName, and DueDate as key-value pairs, each accompanied by a confidence score and bounding polygon. The API call must include "documentType": "INVOICE" inside the processorConfig to activate the invoice-specific extraction model. For UK supplier invoices, verify that VAT fields map correctly to the Tax key and that unit descriptors such as kg, case, and each are captured under the Unit field. Route low-confidence extractions, typically below 0.85, to a manual review queue rather than passing them downstream.
Step 3: Build Approval Rules and Exception Handling for Restaurant Thresholds
Approval logic protects gross profit by flagging anomalies before they enter the books. Industry-standard approval rules for restaurant invoice workflows cover invoice amount thresholds, vendor name, contract price variance, cost centre, and location, for example routing any invoice above £2,000 for senior review. When these rules are layered into a multi-level approval sequence, each threshold or variance triggers a specific approval path that matches your control structure. This structure prevents bypass of budget controls and creates audit trails that multi-site operators rely on during reviews and audits. Within OCI, teams implement these rules as Oracle Integration conditional branches or as custom functions in OCI Functions, which both require developer resource to build and maintain.
Step 4: Map Extracted Data to Vendor Master Records
Three-way matching, which compares the supplier invoice against the original purchase order and the goods-received record, is the recommended standard, with payment approved only when all three documents agree. In OCI, vendor matching relies on a reference data store, typically an Autonomous Database table, that contains supplier names, account codes, and contracted unit prices. The workflow compares extracted invoice fields against this store at runtime. When invoices arrive without a corresponding PO number, the matching process breaks down and invoices accumulate in a review queue that creates accounts payable backlogs. At this point in the build, most restaurant operators without a dedicated integration developer find the complexity outpaces the available resource. The next three steps, pushing data to Xero, connecting POS systems, and generating margin reports, add even more integration work, which pushes many teams to look for a purpose-built platform.
Why Jelly Replaces the Remaining OCI Steps
Steps 5 through 7 of a full OCI implementation, which cover pushing approved data to Xero, connecting POS sales data, and generating margin reports, each require additional Oracle Integration flows, API credentials, and ongoing maintenance. Jelly replaces this entire section of the build with a single platform that performs the full workflow automatically, with no Oracle expertise required. At £129 per site per month on a flat rate with no per-user fees, Jelly onboards a new kitchen in under one week. Invoices arrive by email or photo, Jelly scans every line item including quantity, SKU, price, and tax, and approved data pushes to Xero in one click. The Price Alert feature flags every supplier price movement in the same week it occurs, which gives operators the evidence needed to negotiate credits or switch suppliers quickly.

Steps 5–7 with Jelly: Xero Sync, POS Connection, and Price Alerts
Step 5: Push to Xero Once Jelly has scanned an invoice, a single click sends the digitised, line-item-accurate record into Xero. Syncing invoice data to an accounting system such as Xero removes duplicate entry and keeps books current without manual reconciliation. Jelly’s Xero integration handles this process automatically, and operators report a 90% reduction in bookkeeping time.
Step 6: Connect POS Data Jelly integrates natively with Square, Lightspeed, EPOS Now, and Toast through real-time API connections. Connecting any supported POS takes about five minutes. Open Jelly, click Integrations, sign in to the POS, grant permissions, and select which categories to sync. Item-level sales data flows into Jelly the moment a transaction completes, which enables the Flash Report, a live view of gross profit margin calculated from invoice costs and POS sales. One operator improved gross profit from 65% to 72% within 12 weeks on approximately £500,000 in revenue after connecting their POS.
Step 7: Price-Alert Reports Jelly’s Price Alert feature surfaces every ingredient price increase or decrease and identifies the supplier, the SKU, and the size of the change. This data enables head chefs to call suppliers with hard evidence, claim credit notes, and adjust menu pricing before margins erode. Cairn Lodge Hotel’s head chef Stuart Noble cut food costs by 5% within a month using this feature alone.
Measuring Success with Jelly Instead of Full OCI Build
Operators consistently report the 10–20 hours of monthly admin savings mentioned earlier, along with a 2 percentage point improvement in gross profit within 90 days and immediate visibility into supplier price changes. Amber restaurant in East London saves £3,000–£4,000 per month, which equates to approximately 68× ROI, through invoice automation, price-change alerts, and real-time dish costing. The Howard Arms reached 80% gross profit after implementation, up from a projected 60%. These outcomes arrive within the first week of onboarding, not after a multi-month OCI build.

Frequently Asked Questions
How long does OCI invoice automation take to set up for a single restaurant site?
A complete OCI invoice automation workflow that covers Object Storage ingestion, Document Understanding extraction, approval rules, vendor matching, Xero integration, and reporting requires substantial development time for a single site, assuming access to a developer familiar with Oracle Integration 3 and OCI APIs. Each additional site adds more configuration work. By contrast, Jelly onboards a new kitchen in under one week. Invoices can be submitted by photo or forwarded to a dedicated email address, and price alerts go live within 24 hours of the first invoice being processed.
Does OCI Document Understanding extract line-item quantities and prices from UK supplier invoices?
OCI Document Understanding’s pretrained invoice model extracts Quantity, UnitPrice, ProductCode, Unit, Tax, and other line-item fields from PDF and image invoices, and each extracted value includes a confidence score. The model must be invoked with the correct document type parameter, and low-confidence results need a separate manual review workflow. UK-specific formatting, such as VAT breakdowns, case-pack units, and supplier-specific layouts, can reduce confidence scores and increase the volume of exceptions that require human intervention. Jelly’s invoice scanning is trained on UK supplier invoice formats and handles these variations automatically without extra configuration.
How does Jelly integrate with Xero and common restaurant POS systems?
Jelly integrates directly with Xero for accounting and with Square, Lightspeed, EPOS Now, and Toast for point-of-sale data. The Xero integration enables one-click pushing of digitised, line-item-accurate invoices into the accounting platform, which removes manual bookkeeping. Each POS integration uses a real-time API that delivers item-level sales data the moment a transaction completes. Setup for any supported POS takes about five minutes and follows the same flow across all four systems. Jelly is listed on the Lightspeed marketplace, and all four POS integrations are available to every Jelly subscriber at the standard £129 per site per month flat rate.
What happens when a new supplier invoice arrives that has never been seen before?
In an OCI workflow, an invoice from an unrecognised supplier fails vendor matching because no corresponding record exists in the master data store. The invoice routes to a manual exception queue, where a team member must create the vendor record before the invoice can be processed and approved. In Jelly, new supplier invoices are scanned automatically regardless of whether the supplier has been seen before. Line items are extracted and added to the ingredient database immediately, and the Price Alert feature starts tracking that supplier’s prices from the first invoice. No manual vendor-creation step is required before the invoice contributes to costing and margin calculations.
