Workhand and Obra are the two bilingual apps a small US crew is most likely to meet in the same search, and they are easy to confuse because both were built by people who got tired of software made for offices. They are not the same product. Workhand runs the crew. Obra runs the money.
What Workhand is
A working contractor's operating app. The estimate is built in the driveway and signed on the phone, the deposit lands through Stripe, the crew gets a per-job chat where the estimator writes in English and the field reads in Spanish or Portuguese, hours and miles are logged against the job, and the invoice goes out from the same screen. It ships trade-specific pieces, pool chemical logs among them, and it has app-store apps on both platforms. It is a lot of product, and for a crew that lives on the phone all day, that is the point.
What Obra is
The ledger for each job. Receipts come in from the crew over WhatsApp, in either language, and a person in the office confirms each one to a project and a category. Every project shows what it has collected, what it has cost, what is still committed, and where it is expected to land. Change orders adjust the contract without erasing the original. When the job closes, the numbers are exported for the accountant. Obra does not sell the work, chat with the crew, or clock anyone in, and it does not intend to.
Where the two overlap, and where they don't
Both scan receipts, both speak Spanish, both promise to tell you whether a job made money. The difference is where that promise sits. In Workhand, per-job cost and profit are on the top tier, above the estimating, invoicing and chat that most of its customers came for. In Obra, cost against contract is the first screen of the free plan, because it is the whole product.
The other difference is what the crew touches. Workhand asks the crew to use Workhand, and rewards them with a chat and a time clock that work in their language. Obra asks the crew for nothing new: receipts go to a WhatsApp number they already use, and the office does the rest. Which model fits depends on whether your crew will adopt an app. Some will. Many, in our experience, quietly won't.
Deciding
If the bottleneck is selling and collecting, and the crew is willing to live in an app, Workhand covers a stretch of the business Obra never touches. If the bottleneck is not knowing what a job cost until it is over, start with Obra, free for one project and $12 a seat after, and keep whatever you use to sell the work. The two export to the same accountant either way.
