◯見積もりサイトで使用しています。 スマホ対応のデザインが素晴らしく入力しやすいので、 お客様からのファーストコンタクトとして効果的に機能しています。 ◯実用性が高いPDF拡張(有料オプション)もおすすめです。 5つの初期サンプルの項目修正で簡単にブラウザベースの見積書・納品書・領収書等の作成が可能になりました。 ◯サポートフォーラムでバグ報告した所、1日で修正アップデート対応していただきました。

決済が不要で見積機能だけが必要であれば、細かい配慮の行き届いた、たいへん使いやすいプラグインだと思います。 画像を選択肢のボタンに使うのと条件分岐はWooCommerce単体ではできないので、これだけでも乗り換える価値はあると感じました。 サポート体制も心強く、機能に不満はありますが、今後の完成度の向上と末永いサポートの継続を願って、星5つにします。

デザイン、導入の手軽さは素晴らしいプラグインなのですが 折角のハイクオリティなカートも、 EC機能が付帯していないので実用性が今一つ足りない印象です。 現在、運営している複数のサイトはWelCartでECをしていますが、 WelCartのカートシステムは非常にレベルが低いので、 このプラグインがWelCartプラグインとして連携できるようになれば 有料でも導入したいと考えています。 また物足りない点としては、WordPressはBtoBを目的につかわれることが多い CMSですが、こちらのプラグインは数量毎の卸売りなどBtoB機能の対応が弱いので この部分をできれば少しずつ強化していただければと希望しています。

I think their assumption that the site creator and the site owner are separate is wrong. I am both. It is basically just to difficult to use Aforms as a ‘non-techie’, as you need to be technical on SCSS and other in-depth coding(!). Sorry, it looked promising. Also I was missing a Slider?

見積フォームを作る際によく利用しています。 フロント側もアニメーションを用いて快適に動作するため、クライアントワークでかなり好評でした。 Wordpress側の設定も簡単に行えるため、名称や金額など各項目に改修が入った際も手軽に修正できます。 メールフォームとしても利用できるため、多岐に渡って利用できるプラグインだと思います。 また、開発元も日本であるため、サポート面でも心配はしておりません。 非常に優れたプラグインですので、多くの方に知ってもらいたいと感じています。
