1C-Bitrix Delivery Time Slot Configuration

Imagine an online store on Bitrix is growing, but customers complain that they cannot choose a convenient delivery time. The standard form only offers a date, while the courier service requires slots like '10:00–14:00' or '18:00–22:00'. We've encountered this dozens of times over 5+ years working with Bitrix. For optimal bitrix delivery intervals and delivery slot configuration, our dynamic delivery slots 1c solution ensures efficient booking. One of our clients—a grocery online store—was losing up to 30% of orders due to the lack of time selection. After implementing dynamic slots, conversion increased by 15%, saving them $10,000 annually. Another client, with seasonal peaks, faced double booking under high load—we solved it using transactions and tagged caching. Dynamic slots are 3 times more reliable than static lists under high load.

Our team has 5+ years of experience and has completed 100+ Bitrix projects, delivering reliable solutions. Whether you need bitrix delivery intervals, courier service integration, or a custom checkout form, we can help. For 1c bitrix delivery optimization and delivery slots 1c configuration, we offer tailored setups. To set up delivery time interval bitrix, follow the steps below.

Limitations of the standard delivery service

A common misconception is that enabling the 'time interval' option in delivery settings is enough in Bitrix. In reality, no built-in service has a slot mechanism. You either use order property bitrix (type 'List') or develop a dynamic system on highload blocks. The first option is fast but static. The second is flexible but requires programming.

Implementing dynamic delivery slots with capacity limits

The most common client request is 'slots with limits'. For example, only 10 orders can be accepted for the interval 10:00–14:00. Implementation via the DeliverySlots highload block:

$entity = \Bitrix\Highloadblock\HighloadBlockTable::compileEntity('DeliverySlots');
$slots = $entity::getList([
    'filter' => [
        'UF_DATE' => $date,
        '<=UF_BOOKED' => 'UF_CAPACITY - 1',
    ],
    'select' => ['UF_SLOT', 'UF_CAPACITY', 'UF_BOOKED'],
]);

After order confirmation, UF_BOOKED is incremented inside a transaction to avoid double booking. This is more reliable than frontend checks. For performance, we use tagged caching: the slot list is cached for 1 minute, and the cache is cleared when UF_BOOKED is updated. Dynamic delivery slots with capacity limits reduce double bookings by up to 90% compared to static lists.

How to set up a static interval list in 4 steps

1. Create an order property of type 'List' with the desired intervals (e.g., '10:00–14:00', '14:00–18:00').
2. Attach the property to the delivery service in the 'Commercial Catalog' module settings.
3. In the checkout component, specify the PROPERTIES parameter with the property code.
4. Add a condition to display the property only for the desired delivery service.

This approach suits stores with simple logistics up to 50 orders per day. If you need limits or integration with a courier calendar, use dynamic slots.

What's included in the work

When ordering turnkey delivery interval configuration, we:

• analyze requirements and current architecture,
• choose the optimal option (static list / dynamic slots / courier API integration),
• design highload blocks and configure caching,
• implement a custom slot selection component with validation,
• load-test and deploy to production,
• hand over documentation and train your team.

We guarantee the system won't crash under peak orders—using tagged caching and asynchronous slot checking. All booking update operations are performed in transactions, preventing double entries.

Choosing between static list and dynamic slots

Static list (order property of type 'List') — for stores with simple logistics up to 50 orders per day. Dynamic slots with highload block provide real-time capacity control—3 times better for online stores with seasonal peaks. Integration with a courier calendar (e.g., via the Bitrix REST API of the courier service) fully automates scheduling. Typical cost: $200–$400 for static lists, $500–$1500 for dynamic slots, and $1500–$3000 for full courier integration.

Typical configuration mistakes

• Double booking: occurs if transactions are not used when updating UF_BOOKED. Always wrap the write in Bitrix\Main\Application::getConnection()->startTransaction() and commit only after a successful update.
• Timeouts under peak load: solved by caching the slot list for 1 minute (tagged cache). Configure using \Bitrix\Main\Data\Cache::createInstance().
• Incorrect display of outdated slots: remove past slots daily via an agent. For example, CAgent::AddAgent(...).

Delivery integration: from disparate APIs to a unified calculator in 5 days

A buyer abandons the cart at the shipping stage — they don't see a quote or see an obviously incorrect price. Each such case loses conversion. Automating logistics in 1C-Bitrix solves this problem: we connect delivery services so that the price appears instantly and tracking updates without manager intervention. Over 8 years, we have implemented more than 50 projects with catalogs ranging from 500 to 100,000 SKUs. Average time to connect one carrier is 4 days.

How to accelerate the connection of delivery services to 1C-Bitrix?

The main challenge is not the API call itself, but adapting to the logic of each carrier. CDEK, Boxberry, Russian Post, PEK, DPD — each has its own request format, pricing, and error handling. We use ready-made adapters for each carrier, which reduces integration time by three times compared to custom implementation. Detailed case: an online home goods store (15,000 items) — connected CDEK and Boxberry in 5 days, automated calculation and order creation. Support requests related to delivery dropped by 60%, average order value increased by 8% due to the free shipping indicator.

Why is each carrier's API a separate challenge?

CDEK — volumetric weight and pickup point map

API v2 (/api/v2/calculator/tarifflist) accepts dimensions, weight, and addresses — returns all available tariffs. Pitfalls: volumetric weight is calculated using the formula (L × W × H) / 5000. If physical weight is 2 kg and volumetric weight is 8 kg, CDEK charges by volumetric weight. If not accounted for in the calculator, the buyer sees one price but pays another. The pickup point map is loaded via /deliverypoints. The CDEK widget can be embedded, but it conflicts with Bitrix styles — we draw our own map using Yandex.Maps. Automatic order creation via /api/v2/orders — when placing an order, the request goes to CDEK and returns a tracking number. Printing waybills and labels from the admin panel — via /api/v2/print/orders. Tariffs: warehouse-warehouse, warehouse-door, door-door, express, parcel locker.

Boxberry — extensive pickup point network in regions

The most extensive pickup point network in small towns. API is simpler than CDEK, but there are nuances with cash on delivery and partial redemption. Pickup point map with filters: fitting, card payment, weekend operation. We always check correct handling of response 0 when no pickup points are available.

Russian Post — stability at the cost of speed

API "Sending" — cost calculation, automatic generation of forms 103 and 116, tracking by tracking number. Tariffs: parcel, printed matter, EMS. International shipments. API is slower than commercial carriers — we set 10-second timeouts, use asynchronous Bitrix agents for status updates.

PEK — heavy loads and groupage

When you need to ship a sofa or equipment. Calculation of groupage cargo, insurance, crate. Delivery to terminal and door-to-door. PEK terminal indices are loaded into an infoblock for auto-completion.

DPD — express delivery with time slots

DPD across Russia and abroad. Delivery within a selected time interval, return of signed documents. In the calculation, we account for volumetric weight using the formula (L×W×H)/4000 — different from CDEK.

How to combine different carriers in a single calculator?

We use a hybrid approach: an aggregator module that routes requests to different APIs and normalizes responses. This allows comparing tariffs in real time without switching between personal accounts. The module response has a unified structure: tariff name, price, delivery time, delivery type. Tagged caching: when module settings change, only the cache for the selected city is cleared, the rest remains. We hook the OnBeforeDeliveryCalculate event to a custom handler — this replaces the standard delivery logic.

Cost calculation: what pitfalls are encountered?

The automatic calculator sums the physical and volumetric weight of items in the cart, adds packaging weight, and selects the largest. Sounds simple, but:

• Dimensions must be filled for each item. No dimensions — no calculation. A catalog of 10,000 SKUs will inevitably have items without dimensions — we set default values (e.g., 0.1×0.1×0.1 m) and warn the manager via a mail event.
• Promotions and free shipping thresholds — flexible configuration: by order amount, for VIP customers, with a specific payment method. Implemented via custom cart properties.
• The indicator "Only N rubles left for free shipping" — a simple thing, but increases average order value by 5–12%. Calculated by order amount and nearest threshold, displayed in the cart template.

How to automate tracking, pickup, and courier delivery?

Tracking. Automatic polling of carrier APIs — a Bitrix agent checks order statuses every 30 minutes for orders with STATUS_DELIVERY != 'DELIVERED'. Upon change — update order status in the system and notify the customer (email, SMS, push). Built-in tracking page in the personal account — the customer doesn't need to go to the carrier's website. Map with current location, estimated delivery date, redirection option.

Pickup. Own pickup points on the map: addresses, schedule, contacts. Search for the nearest by customer address. Real-time availability check, reservation until a specific time. QR code for quick pickup and SMS about readiness.

Courier delivery. Delivery zones with different costs. 2-hour slots, courier schedule management, order limit per slot. Same-day delivery — orders accepted until 14:00, express in 2-4 hours with a surcharge for urgency. Integration with navigation for route optimization.

Multi-warehouse. Multiple warehouses with addresses and service zones. Automatic selection of the shipping warehouse based on the customer's address — priority to the nearest one that has all ordered items. If one warehouse doesn't have everything — split order across warehouses (multi-delivery). Stock synchronization via 1C or WMS (CommerceML), using OnBeforeBasketAdd event to check availability.

Comparison of transport companies

What stages does connecting delivery services consist of?

1. Logistics analysis (1–2 days) — geography, average weight, order volume, 1C integration. We recommend a combination of carriers.
2. API connection (3–5 days per carrier) — setup of calculations, pickup point maps, automatic order creation via agents and events.
3. Tracking setup (1–2 weeks) — status update agents, notification templates, tracking page.
4. Testing (2–3 days) — testing with real addresses, comparing tariffs, checking for incorrect calculations, load testing.
5. Deployment and training (1 day) — module release, access handover, manager training.
6. Warranty support (1 month) — bug fixes, configuration adjustments, cache fine-tuning.

Estimated implementation timelines

Timelines depend on the number of carriers, catalog complexity, and need for integration with 1C/ERP. Cost is calculated individually — consider the savings: reduction in delivery operational costs by up to 40% and reduction in support requests by 60%. For example, one client with an electronics store (20,000 items) recouped investment in 3 months due to reduced "forgotten" orders.
