A property is ready to market, the photos are approved, and the vendor expects to see it live quickly. The last thing your team needs is another portal login, another manual form, and another chance for the details to differ from the listing on your website. An OnTheMarket listing upload service removes that repeated work by sending the right property data from one managed source to your portal account.
For busy estate and letting agencies, speed matters, but accuracy matters just as much. A listing with the wrong rent, an outdated availability status, or missing floorplan can create unnecessary calls, lost inquiries, and awkward conversations. A reliable feed gives your team a practical way to keep OnTheMarket updated without making portal administration a full-time job.
What an OnTheMarket listing upload service does
An upload service takes property data from the place or source your agency already manages - whether that is a CRM, property management platform, XML data feed, BLM data file, API Web Service or website dashboard - and converts it into the format required for portal publication. It then delivers sales, lettings, new homes, commercial, or overseas listings to OnTheMarket through the appropriate feed connection.
The operational benefit is straightforward: update a property once, then distribute it. When the asking price changes, a property is let agreed, or a new brochure is added, the amended data can be sent through without someone logging in to repeat the change by hand.
That is particularly useful for agencies running several branches or managing a large stock list. A central dashboard can keep records organized by office while giving head office visibility of what is being advertised. It also reduces the risk that one branch publishes a different description or price from another system.
Why manual portal updates become expensive
Manual entry can look manageable when an agency has a small number of listings and one advertising channel. The problem grows quietly. Each new portal adds another set of logins, image uploads, mandatory fields, status changes, and checks. If one person is away or a listing is changed late in the day, the work can sit in a queue.
The direct cost is staff time. The less obvious cost is inconsistency. A property might be marked sold subject to contract on one channel but still appear available on another. A newly reduced price might reach your website before the portal. Buyers and tenants rarely care why the mismatch happened. They simply lose confidence or contact another agent.
A feed-based workflow does not remove the need for good data at source. It does, however, make that source the place your team focuses its effort. Instead of correcting the same record across multiple advertising sites, staff can make one accurate change and allow the distribution process to do the repetitive part.
The data behind a dependable upload
Portal advertising is more than a headline, price, and a selection of photographs. A useful OnTheMarket feed needs structured information that can be read consistently by the portal. This usually includes property type, transaction type, address display settings, price or rent, bedroom and bathroom counts, description, key features, images, floorplans, EPC information where applicable, tenure, council tax details, and listing status.
For lettings, the details often go further. Deposit, minimum tenancy period, furnishing information, available date, and rental frequency all need to be clear. New-build and overseas listings can introduce their own fields, such as development names, plot references, completion dates, currencies, or location data.
The service should validate and map this information before publication wherever possible. Field mapping is the technical work that tells the feed where each item from your CRM or source file belongs on the destination portal. It sounds behind the scenes, but it is what prevents a bedroom count being missed, a description appearing in the wrong field, or an image feed failing after a software change.
Choose the right upload method for your agency
There is no single best setup for every business. The right option depends on where your listings are maintained, how often they change, and how much control your team wants over the process.
Remote feed imports for established CRM workflows
If your agency already uses a CRM, website CMS, or property software package, a remote import is usually the fastest route. Your system exports data through XML, BLM, API, Jupix, Vebra, or another compatible format. The upload platform checks that feed regularly, processes changes, and sends the latest approved data to the relevant portals.
This is the sensible choice for agencies with active stock, multiple branches, or frequent status changes. It keeps the workload low because staff continue using the system they know. With frequent import checks, sometimes as often as every 15 minutes, updates can move quickly from your source system to publication.
Manual dashboard entry for simple control
Manual entry can suit a new agency, a developer with a limited number of plots, or a business whose current software does not export a usable feed. Rather than building an integration before you are ready, your staff can create and manage listings in a secure dashboard and choose the channels where they should appear.
The key is to be realistic about volume. Manual entry is quick and simple for a manageable portfolio, but it may not be the best long-term answer for hundreds of fast-moving lettings. A service that supports up to 600 manual listings gives smaller teams room to grow without forcing an immediate software change.
API integration for software providers and custom platforms
Property software companies, portals, and larger operators may need more control than a standard import provides. An API integration can support automated two-way workflows, custom data structures, and direct connections between a product and advertising channels.
This route takes more planning. Your technical team needs to agree on field mappings, image handling, status rules, error reporting, and testing. But once it is set up correctly, it can provide dependable distribution infrastructure without each software user having to build separate portal connections.
What to check before your listings go live
An OnTheMarket listing upload service should make publication easier, not hide problems until a property fails to appear. Before launch, check that your portal account is active and that you have the necessary commercial agreement with OnTheMarket. A feed provider can distribute your data, but it does not replace portal membership or any eligibility requirements set by the portal.
You should also confirm which listing types will be sent, which branch or office owns each property, and how statuses are mapped. For example, decide whether withdrawn properties should be removed immediately, whether let agreed listings remain visible, and how price reductions are reflected. These choices affect both compliance and lead quality.
Image quality deserves attention as well. A feed can send images quickly, but it cannot make weak photographs sell a property. Use correctly sized images, place the strongest photo first, and make sure floorplans and brochures are attached at source. If the source record is complete, the portal record has a much better chance of being complete too.
The value of support when something changes
Property feeds are not a set-and-forget technical project. CRMs change export formats, portal requirements evolve, staff add new branches, and agencies adopt new advertising channels. When that happens, responsive human support can save a great deal of time.
Look for a provider that can explain a failed import in plain language and work with your software team when the issue is technical. You should be able to see whether an import has been received, whether listings have processed, and whether any records need attention. Clear reporting is far more useful than discovering a missing property after a vendor calls.
Estate Agent Feeds is built around this practical model: a central place to manage distribution, flexible imports for different systems, and direct phone and email support when you need an answer. With no long-term contract and pay-as-you-go plans, agencies can choose a setup that fits their current stock and scale it as their marketing activity grows.
Send once, then keep control
The best portal workflow is not about adding more technology for its own sake. It is about giving your team fewer repetitive tasks and a clearer view of where every listing is being advertised. A properly configured feed can send the same accurate property record to OnTheMarket and other chosen channels while your staff remain focused on instructions, viewings, applicants, and clients.
Start with clean source data, agree the rules for statuses and branches, and test a small group of listings before moving your full portfolio. Once the process is working, portal advertising becomes the quick, simple part of marketing a property rather than another daily admin burden.
