RESO Web API and RETS feeds ingested, normalised across multiple MLS boards, and kept current — with listing status, price history and media handled properly rather than re-scraped nightly.
MLS/IDX feeds, lead routing, transaction pipelines and commission splits — built for brokerages, not generic sales CRM.

Real estate CRM development connects MLS and IDX feeds, routes portal leads, tracks transaction milestones and calculates commission splits — workflows generic sales CRM cannot handle. Codazz builds brokerage and PropTech CRM in 10–14 weeks with RESO Web API integration and fixed-price scope.

Ask our teamCost is driven by agent and office count, how many MLS boards you feed from, how much of the transaction lifecycle the system carries — commission and split calculation and compliance document workflows in particular — and whether you need a multi-tenant platform with consumer-facing search. We scope that in a free session and quote fixed-price against a written specification.
Yes — RESO Web API and legacy RETS, across multiple boards, with normalisation so a listing looks the same regardless of which board it came from. We handle status changes, price history, media, and the per-board display rules your IDX licence requires. Board approval timelines are usually the critical path, not the engineering, so we start that paperwork in week one.
For a small team, those products are usually the right answer and we will say so. Custom real estate CRM development earns its cost when per-seat pricing across a large agent roster has become a major expense, when your split and commission model does not fit any product, when you need transaction compliance evidence that the product does not produce, or when the CRM is itself the product you are selling.
Yes. Splits, team overrides, referral fees, annual caps, post-cap rates and brokerage retention are calculated automatically per transaction, with statements agents can reconcile line by line. This is consistently the feature that removes the most manual work from brokerage back offices.
Ten to fourteen weeks for a team CRM, four to six months for a full brokerage system with transaction management and commissions, and six to ten months for a multi-tenant PropTech platform. MLS feed integration starts early in every build because feed quirks are best discovered while there is still time to design around them.
Yes. Contacts, leads, listings, activity history and transaction records are profiled, cleaned, de-duplicated and migrated with a verified dry run first. We roll out by team rather than brokerage-wide on day one, so problems affect one office rather than every agent at once.
