How can we help?
General
Does Hevea Flow work offline?
Yes. The app works normally in the field without signal and syncs everything automatically as soon as the connection comes back.
Do rubber tappers use Hevea Flow too?
Yes. They have their own app, Hevea Flow Sangrador. You invite the rubber tapper to your property and they start receiving the tapping and stimulation schedule and tracking their own performance.
How do the rubber tapper's challenges and points work?
The rubber tapper completes daily, weekly and monthly challenges, such as doing the day's tapping or recovering a delayed tapping, earning points and leveling up. A tapping only counts after you confirm it. You can follow each tapper's points, level and challenges on their profile.
Can I issue invoices through the app?
Only Brazilian electronic invoices (NF-e), and for now only for properties in the state of São Paulo, Brazil. You issue the NF-e from a sales order or as a standalone invoice, track its status with the tax authority (SEFAZ) and keep the DANFE and XML in the app.
Can I see Hevea Flow in action before signing up?
Yes. Book a demo and our team will show you the app applied to your property's routine.
How much does it cost?
Prices depend on the plan you choose. See the plans.
Production
See the areaHow is tapping frequency calculated?
Frequency = (completed + recovered tappings) ÷ valid tappings × 100. Valid tappings are the scheduled ones minus excused and canceled ones. Example: out of 100 scheduled tappings, 10 were excused due to rain; the rubber tapper did 85 of the remaining 90, so their frequency is 94.4%.
Do I have to build the rotation by hand?
No. The app suggests a rotation that spreads the trees evenly across the days and groups nearby tasks. You can move tasks and rows between days and mark rest days.
What about rainy days when tapping isn't possible?
Record the rain in the app and mark the day's tappings as excused. Excused tappings don't count against the rubber tapper's frequency.
Does the rubber tapper need internet to record a tapping?
No. The rubber tapper app works without signal, maps included, and sends the records as soon as the connection comes back.
Tapping quality
See the areaWho does the assessment?
Anyone on your team with access to the Production module in the app, such as you, a supervisor or the technical consultant.
Can I use my own criteria?
Yes. Besides the standard questionnaire, you can create your own forms, with questions, weights and pass criteria.
Does the rubber tapper see the score?
Yes. In the rubber tapper app they can check the assessments they received, with the score for each tree and photos of the panel, and follow their own progress.
Can I assess without internet?
Yes. The app works normally in the field and syncs the assessments as soon as the connection comes back.
Costs
See the areaDoes it work for activities other than the rubber plantation?
Yes. Work orders cover the whole farm. The same tractors, operators and inputs can serve rubber growing, reforestation or another activity, each in its own cost center.
How is fuel included in the cost?
You record each machine's refueling. The app spreads the fuel cost across the orders completed in the month, in proportion to the machine's hours of use.
What if an input runs out of stock?
The app tracks the balance of each input, subtracting what has been used and what is reserved for planned orders. If the balance isn't enough, order planning warns you before you count on an input you don't have.
If I change a resource's cost, do old orders change?
No. The new reference cost applies to future orders. Orders already recorded keep the cost from that time.
Collection and sales
See the areaWhat is the DRC 53% weight?
DRC is the dry rubber content of the load, stated in the buyer's lab report. The DRC 53% weight is what the load would weigh at 53% dry rubber, which is the basis on which the price is quoted in Brazil. The app does this calculation for you.
What do I need to issue invoices through the app?
Invoicing is for Brazilian electronic invoices (NF-e), and for now it is available for properties in the state of São Paulo, Brazil. It takes a one-time property setup: issuer details, digital certificate and invoice numbering. After that, you issue invoices straight from your orders.
Is the production share with the rubber tapper automatic?
Yes. You set the sharing rule once, with percentages by plot age, and the app applies it to every collection. The rubber tapper sees in their app how much they produced and how much they received.
Can I invoice a sale that wasn't recorded in the app?
Yes. Besides invoicing from an order, the app lets you issue a standalone invoice.
Rubber tappers
See the areaHow does a rubber tapper join my property?
They download the Hevea Flow Sangrador app and create an account. You send an invitation from the Producer app, they accept it and start seeing your property's schedule.
Can a rubber tapper see other tappers' data?
They see their own production, assessments and performance. For their colleagues, they only see the name, position and score in the property ranking.
How are the rubber tapper's points calculated?
Each completed challenge is worth points, and points make the rubber tapper level up. Tapping-related challenges only advance after you confirm the tapping in the app.
What if the rubber tapper leaves the property?
Their link to the property can be ended. From then on, they no longer see your property's schedule and data in their app.
Indicators and reports
See the areaWhere do the indicator numbers come from?
From the records your team makes every day: tappings, collections, assessments, orders and rainfall. The app doesn't estimate or make up any number.
Can the AI get the report numbers wrong?
The AI doesn't calculate anything. All numbers are calculated by the app from your records and delivered ready. The AI only writes the reading: what happened, why and what to do.
Why is production shown adjusted to DRC 53%?
Because rubber moisture varies from one collection to another. Adjusting to 53% dry rubber, the basis on which the price is quoted, makes collections comparable.
Are the AI reports included in every plan?
No. The AI reports depend on the plan you subscribe to. See the plans.
